Why Websites Are Sometimes Blocked

The Internet seems like a big free highway: I sat down, drove, flew to the right site. But sometimes, instead of the desired page, there is “Access denied”, “This site is unavailable” or an eternal download without a finale. Who blocked the road? There are many reasons, and they work at different levels. So let’s find out together how to unblock a website.

Briefly about the scenarios:

• Technical: DNS is broken, the certificate expired, the site has moved, and your ISP still “does not know” the new address.
• Policies and Regulations: A school, office, or Wi-Fi owner considers some content undesirable and turns on filters.
• Legal and Licenses: courts, regulators, and copyright holders oblige providers to block access to domains or IP addresses.
• Protection against abuse: the site itself cuts off access from “suspicious” networks, regions, or IP addresses. For more info about IP address and what it is please check our article.

It is important to look from both sides at once. From the visitor’s side, the lock feels like “they won’t let me in” — the page doesn’t open, a redirect to a stub, a captcha, and strange TLS errors. On the part of the owner, this is “users are not reaching me” — a drop in traffic from entire regions, sudden 403/451, a surge in complaints “the site is not working”.

The same problem, but different levers of influence: the user experiments with his network and settings, the owner experiments with DNS, CDN, WAF rules and relations with providers.

One more caveat: blocking is not always an “evil barrier.” This is often a side effect. For example, your IP turned out to be on someone else’s “blacklist” due to past abuses at this address (dynamic IP issuance from providers is common), or a corporate proxy mistakenly listed the site in the “social networks/games” category, and it disappeared for the entire company.

Bottom line: before “breaking down the wall”, it is useful to understand who put it up and why.

Types of Website Locks

Restrictions come in different calibres, from fine filtering by page address to rough chopping off entire subnets. Let’s look at the levels and signals by which they can be recognized.

By IP (device or server address). This is the most direct way: they take a specific IP address and enter it in “deny”.

• Client block: your home network or mobile IP is not allowed on the site (403, endless captcha, “access denied”). This is often the anti-fraud/anti-bot logic of a website or a corporate/campus firewall.
• Server block: your ISP or government filter cuts off connections to the server IP of the site — the page does not load at all, it pings “silently”, the connection is terminated at the TLS stage.
• Distinguishing features: the site does not open from this connection, but opens through another network/operator. The traceroute ends “at the perimeter”.

By domain name (DNS blocking). DNS is the “phone book” of the Internet. If the book says “nothing” or “wrong” instead of the number, you won’t get through to anywhere.

• Methods: NXDOMAIN return (“there is no such domain”), IP substitution with a stub, redirect to a warning.
• Where it happens: at providers and in the state perimeter; sometimes in school/office controllers.
• Signs: the same site opens if you switch the DNS resolver (the system remains “blind”). Different devices on the same network see the same “wrong” IP.

By content (URL filters, keywords). A more subtle “needle”: traffic is allowed through, but some paths are blocked.

• URL categories: “social networks/games/videos/18+” – classic corporate proxies and parental controls.
• Filtering by words/patterns: requests with certain strings in the address or body are cut off (for example, downloads, torrents, admin panels).
• DPI/SNI: deep packet analysis can look at the SNI field in TLS (hostname) and cut through it, even if the rest is encrypted.
• Signs: the main page opens, and specific sections/files are 403/404 or “policy blocked”.

Using geo constraint. Geo is about “where the network thinks you are.”

• Site-side geofencing: streaming/media/licensed services show content only to certain countries (HTTP 451 “Unavailable For Legal Reasons” or “content not available in your region”).
• Geo—blocking by the provider/country: on the contrary, at the operator level, communication towards domains/subnets is cut for all subscribers in the region.
• Signs: everything opens through another region (or mobile operator); IP geolocation in the services shows the “wrong” region.

Reasons For Blocking The User

Why did your website suddenly stop opening as a visitor? Here are typical, mundane explanations — from the most banal to rare, but revealing.

Local restrictions: school, office, public network

• Corporate proxies and security gateways mark sites by category (Social, Streaming, Gambling, etc.) and block “excess” in order not to waste bandwidth and keep employees in a work context.
• School/university networks often cut social media and video hosting sites during school hours.
• Guest Wi-Fi in cafes/airports can be “whitelisted” (not logged in yet) or with very strict categories.
• At the device level: parental control, antivirus with web filtering, browser extensions (ad-block/anti-tracker) can “overdo it” and close the desired domain.

What it looks like: the website opens on the home LTE, and in the office there is a 403/white page/provider stub. It loads on one browser, but not on the other (the extension cuts requests).

Geo-blocking for certain countries

• Licenses and copyright holders: video services, sports broadcasts, music catalogs — access strictly by country.
• Export restrictions and sanctions: Some SaaS/clouds do not serve users from certain regions.
• Taxes and compliance: local versions of sites may not be available where there are complex data processing requirements (and the service is “reinsured” by the block).

Symptoms: “This content is not available in your location”, “We do not support your region”. Through another operator/roaming — everything is ok.

Blocking by the provider or the state

• Court decisions/Domain registries — the telecom operator is required to filter routes to domains/subnets.
• DNS substitution on the provider’s resolvers — the domain is “transferred” to a stub.
• DPI filtering — blocking by SNI/categories/keywords even inside HTTPS traffic.

How it feels: the site is equally “dead” on all devices and browsers on this network. But it opens via another network/ operator / during the trip.

Bonus: “unnoticeable” reasons that are often overlooked

To make the text honestly practical, I will list a number of other reasons that disguise themselves as “blocking”, although they are not formally it – but the user feels the same:

• Cache and “stuck” DNS. The site has already moved on one device, but not yet on the other (TTL of the old records).
• Expired SSL certificate. The browser won’t let you in, it will show you a scary page about an insecure connection.
• Strict WAF of the site. Suspicious headers/frequent requests/a non-standard User Agent — and you get a 403 or an endless captcha.
• An IP with a “dirty” history. You got the dynamic address from the provider after the “noisy neighbor”; the site sees the IP reputation and closes the door.
• Old version of TLS/browser. The server requires modern TLS, but you have a “dinosaur” and the handshake doesn’t add up.
• Extensions and defenders in the browser. Ad-block/anti-tracker cuts CDN scripts, and the site “breaks” out of the blue.
• Moving to IPv6/v6 only. The provider / router does not know how — the site is “unavailable”, although according to v6 it is the most alive of all the living.

Reasons For Blocking For The Site Owner

Sometimes a website “disappears” not because someone maliciously disabled it, but because of quite mundane reasons.

1. The most common is a DNS failure or incorrect configuration. The domain was extended at the wrong time, the NS servers were changed, but they did not wait for the records to be distributed, they mixed up A/AAAA and sent traffic “nowhere”, DNSSEC was turned on, but the keys did not match – and now some users do not resolve your domain or resolve incorrectly. From the outside, it looks like “the site does not open”, but inside it is a common error in the zone.
2. The second group of reasons is reputational blockages. The IP or domain could be blacklisted due to spam (often from a compromised email script on the site), malicious code (hacked plugin/CMS), phishing pages, aggressive advertising. On shared hosting, the entire “entrance” suffers: one neighbor makes a noise – the entire IP pool is under suspicion. The result is warnings in browsers, blocks from search engines, complaints from providers.
3. And the third is infrastructure restrictions and automatic defense. CPU/memory overruns, process limits, “clogged” inodes, excessive traffic — hosting begins to stifle the project: 429/503 responses, connection failures. Under DDoS, WAF/CDN protection is enabled: thresholds are triggered, and some legitimate requests receive 403, captcha, or geo-block. Plus the human factor: misconfigured firewall rules, country bans, sloppy redirects, expired TLS certificate. All this is not about the “universal conspiracy”, but about very specific settings, logs and metrics that need to be put in order.

How To Understand Who Blocked Access And Where

The best strategy is to move in layers, from the user to the server. First, we check the symptom: the site does not open only for you or is “lying” for everyone. Open the page from your home Internet, mobile network, or via VPN.

If it is loading in one place and not in another, it means that the block or failure is local. Services like downforeveryoneorjustme.com They help you quickly understand the general status, but they do not replace a full-fledged diagnosis.

Next is DNS. If the domain does not resolve (NXDOMAIN, SERVFAIL), the problem is on the side of the/NS zones. If it resolves to the wrong place, we are looking at A/AAAA/CNAME. There is an IP — we are trying basic network connectivity: ping (not always indicative), more useful — traceroute/mtr: on which hop does the route “die”? The break is at the beginning — provider/routing; at the end — hosting/CDN.

The connection is established, but the browser swears at the certificate — a question about TLS (expired / wrong domain/ SNI). We get to the HTTP level: the response codes say a lot. 403 with a WAF/CDN signature — the security system considered the request suspicious. 429 is the frequency limit. 5xx is a server error. 451 — legal restrictions.

Cloudflare has 52x codes (522/524) — origin does not respond. The provider’s warning page is a provider block. Captchas “at every step” with a clean server — filtering on the side of protection/ anti-bot rules.

If you are the owner, complete the diagnosis with logs: access/error logs of the web server, WAF audit, CDN events, hosting metrics (CPU/RAM/disk/traffic). The presence of GeoIP/ASN deny records, 4xx/5xx spikes, and connection graphs are direct markers of which level the lock was “clicked” and who closed it.

How to Unblock a Website Methods For The VPN User

A VPN is a private “tunnel” on top of the regular Internet. Your data is encrypted on the device, goes to the VPN provider’s exit point, and from there it gets to the website. From the outside, the server sees not your home IP, but the IP of the VPN node.

This has two effects: the ISP/local network stops seeing what exactly you are opening (they only see the fact of an encrypted tunnel), and the sites see you “as a user from another part of the world.” This helps to bypass geo-blocks, provider-level filtering and some of the anti-bot barriers, and at the same time protects against interception in public Wi-Fi.

There are free and paid options. Free ones attract a zero price, but they limit speed and traffic, queue up, show ads, and often use overloaded public IP addresses that are already blacklisted. In the worst cases, they collect and sell telemetry, implement tracking, save on encryption and do not have a “kill switch” (when the tunnel breaks, traffic suddenly goes into the open).

Paid services usually provide modern protocols (WireGuard/OpenVPN), their own DNS, distributed nodes, lock resistance, router support, and a killer switch.

It’s important to understand the boundaries: A VPN doesn’t make you “invisible.” Websites can recognize traffic by behavioral signs, anti-fraud systems often treat VPN IP pools harshly (captchas, payment bans), and streaming services block known addresses. Browser extensions called “VPNs” often turn out to be ordinary proxies (they encrypt only browser traffic).

If you need to be reliable, a VPN system client, a well—configured DNS, and careful habits are better (without WebRTC leaks and unnecessary browser identifiers). Then VPN becomes not a “magic button”, but a clear tool that makes access more stable and safer.

How to Unblock Websites Via Proxy Servers And Tor Browser

How does a proxy differ from a VPN?

• The level of work. A proxy is a “transfer base” for a single application (browser, Telegram client, media player). VPN is a “tunnel” for all device traffic.
• Encryption. The classic HTTP/HTTPS/SOCKS proxy does not encrypt traffic by itself (it only encrypts your site if it is HTTPS). A VPN encrypts the entire stream at the system level.
• DNS and “leaks”. The proxy often does not redirect DNS requests – the provider still sees which domains you are asking for. A VPN usually takes DNS inside the tunnel as well.
• Flexibility of protocols. SOCKS5 is able to bypass any TCP connection (some implementations include UDP), HTTP proxy is suitable only for the web. VPN works transparently with any application protocols.
• Speed/load. A proxy is simpler and can provide less overhead; a VPN provides more privacy, but requires encryption.

When Tor is convenient and when it is not.

• Convenient
  • when maximum anonymity is needed (strict isolation of tabs, tracking protection, onion routing),for accessing resources blocked by countries/providers,
  • for reading, researching, and working with sensitive topics (without logging into personal accounts).
• Inconvenient
  • for streaming, games, and calls, the speed and delays are higher than usual,
  • when logging in to banks/stores, there is an increased risk of captchas and blockages,
  • if you need a stable “white” IP, Tor exit nodes are often banned.

Important: Tor encrypts the path to the exit node, but the last “leg” to the site is the regular Internet. All unencrypted HTTP output can be intercepted. Use only HTTPS and the Tor Browser itself (it isolates the browser’s fingerprint).

The risks of public proxies.

• Interception and substitution. Hosting a “free” proxy can read logins, embed ads/scripts, and change responses.
• Collecting logs. Requests and headers can be written to a file — hello deanonymization.
• Poor IP reputation. Public IP addresses are often blacklisted — get ready for 403s, captchas, and limited functionality.
• Legal tails. If there was illegal activity using this IP, you share your reputation with others.
• How to minimize harm: use HTTPS sites, avoid logging into important accounts, prefer trusted providers and authenticated SOCKS5/HTTPS proxies, do not keep proxies in “always on” mode.

How to Unblock Websites by Changing DNS Settings

Popular DNS providers.

• Google Public DNS: 8.8.8.8 / 8.8.4.4
• Cloudflare DNS: 1.1.1.1 / 1.0.0.1 (there is DoH/DoT, fast resolution)
• OpenDNS (Cisco): 208.67.222.222 / 208.67.220.220 (there are filters/parental controls)

How changing DNS helps to bypass blocking.

• If the PROVIDER substitutes DNS responses (shows a “stub”, gives the wrong IP or NXDOMAIN), switching to external and/or encrypted DNS (DoH/DoT) returns the correct entries.
• With geo-blocking linked to local DNS pools, another resolver may give up another CDN node, which sometimes “opens” the restriction.
• But: if the block is at the IP/port/SNI/DPI level, DNS alone will not save — you will need a VPN/proxy.

Advantages of the method.

• Simplicity and speed. It changes in a couple of minutes on the device or router, often improves the response time.
• Stability. External resolvers are usually more fault tolerant than the “boxed” DNS providers.
• Security. DoH/DoT support makes it difficult for the provider to see and substitute your DNS queries; OpenDNS has phishing filtering.

Disadvantages and pitfalls.

• Not a universal bypass. DNS is powerless against IP blocking and DPI filtering.
• Confidentiality. If you share your requests with your chosen DNS provider, read the privacy policy.
• CDN and geography. Sometimes a DNS change changes the “entry point” to the CDN — different content/speed is possible.
• System caches. After changing the DNS, do not forget to clear the cache (reboot/ipconfig /flushdns/ network restart), otherwise the effect will not appear immediately.

Where to change.

• On the device: Wi-Fi/Ethernet network settings → “DNS manually” → add addresses, delete old ones.
• On the router: WAN/DHCP → DNS Servers → enter new addresses (it will affect all devices on the network).
• Encrypted DNS: in modern operating systems/browsers, enable DNS over HTTPS/TLS and select a provider from the list.

How to Unblock a Website With Mobile Internet And Access Points

When mobile data is the way out.

• Local bans. Is the network cutting the necessary sites or ports in the office/cafe/campus? Turn on the mobile Internet and bypass the local Wi-Fi rules.
• A broken router/ISP. The home Internet has “crashed”, the DNS at the provider is weird — the mobile network provides an alternative route.
• A different IP pool. Many blockages are tied to fixed home IP/ASN addresses. The mobile operator gives a different ASN and address dynamics, which often “decouples” the filters.

Creating a personal access point (tethering).

• Turn on the “Modem Mode” on your phone/Access point”, set a complex password and WPA2/WPA3 encryption.
• Connect your laptop/tablet to regular Wi-Fi.
• Keep an eye on the data transmission indicator and signal strength — stability is the key here.
• If the operator restricts tethering, sometimes a USB modem or the operator’s proprietary application helps.

When it helps and when it doesn’t.

• Helps:
  • with problems specifically in your Wi-Fi network/router/provider,
  • with geo-blocking (if the mobile network is “visible” as another region/provider),
  • when a backup connection is needed for work/payments.
• Useless or weak effect:
  • if the resource is blocked at the country level or uses a hard DPI/SNI filter, the mobile network of the same region is no better.,
  • if the service itself blocks mobile IP addresses (anti-fraud, limits),
  • with poor coverage, heavy load of the base station, strict traffic limits.

Something to remember.

• Cost and limits. Videos/updates “eat up” gigabytes — check the tariff and balance.
• Security. Do not leave the access point “open”, change the password, and do not reveal the network name, which is easy to identify you.
• Battery. Tethering — Voracious: Keep your charger/power bank handy.
• Operator’s policy. Some providers cut the speed during distribution or after the threshold — plan with a margin.

Total: mobile Internet is a fast “plan B” that often solves local bans and disruptions. But if the restriction is deeper (IP ban, DPI, legal blocks), you will need more “heavy artillery” – VPN, correct DNS and accurate network settings in combination.

How to Unblock a Website on iPhone: Step-by-Step Guide with No Dry Instructions

Imagine: you open Safari on your iPhone, enter the address of your favorite website, click “go” — and instead of the usual page, you get a dry message: “Access is restricted.” And then a slight indignation awakens inside: a phone for a lot of money, the Internet is at hand, and you can’t get to the site. Why? And most importantly — how to get around it.

In fact, blocking can occur at three different levels:

1. On the iPhone itself, through built-in restrictions (screen time, parental controls, and content filters).
2. At the ISP or network level, where your carrier or Wi-Fi provider restricts access to certain websites.
3. On the website itself, if it bans users based on their IP address or region.

And here’s where it’s important to understand: an iPhone is not just a “screen with icons,” but a whole set of hidden doors and levers that can be manipulated.

For example, if a website is blocked due to content settings, the path is Settings → Screen Time → Content Restrictions. Here, you can check if age or category filtering is enabled. Sometimes, simply unchecking the box is enough to bring the website back to life.

If the block comes from the network, you’ll need to “disguise” yourself on the internet by changing your IP address. This is where VPN apps come in (they create a secure tunnel and mask your location). There are dozens of them available for iPhone, and it only takes a couple of minutes to connect: download, select a country, click “Connect,” and Safari will think you’re somewhere else in the world.

 If a website has banned your IP address, you can use mobile data or a hotspot from another device. Sometimes, switching from Wi-Fi to LTE is like changing doors: one may be closed, but the other is wide open.

The main thing is to remember: there is no “magic button to unlock everything” in the iPhone, but there is a set of techniques that, in the right combination, solve the problem in a couple of minutes.

What Can The Site Owner Do — DNS Correction

Quick diagnosis (5 minutes).

• Check who manages the zone: does the registrar have the correct NS? (it happens that they were changed, but the zone was not moved).
• Let’s see what the domain really corresponds to: dig +short A yourdomain.com , dig +short AAAA yourdomain.com , dig +short CNAME www.yourdomain.com .
• If the responses are different on different networks, the problem is in the cache/distribution or DNSSEC.

Checking key records.

• A/AAAA (base):
  • A is the IPv4 address of your server/CDN.
  • AAAA — IPv6 (if available). If the server is not listening to IPv6, remove AAAA, otherwise some of the traffic will fall into a “black hole”.
• CNAME (more often for www):
  • CNAME is not allowed at the top of the zone (root). If the provider promises an “ALIAS/ANAME” is their “flat” CNAME, it is acceptable.
  • We exclude loops: www → @ and @ → www — classical infinity.
• MX/TXT (side effects, but important):
  • MX does not affect the loading of the site, but errors sometimes “suggest” that the zone as a whole is broken (broken priority, incorrect host).
  • TXT (SPF/domain verification from mailers/CDN) — for integrity.

Common causes and quick fixes.

• Incorrect IP in A/AAAA. We are updating to the current one (from the hosting panel/CDN).
• DNSSEC (SERVFAIL). Invalid DS record at the registrar → either synchronize keys, or temporarily disable DNSSEC, restore work, and then enable it again.
• The TTL is too high. Before migrations, set the TTL to 60-300 seconds, switch, and after stabilization, set it back to 1-4 hours.
• Separated NS. The zone is managed by one provider, while the NS in the registry is managed by others. We move the zone or adjust the NS at the registrar.

Restoring accessibility through the hosting panel.

• Make sure that the domain is linked to the correct virtual host (vhost) and root folder. Often, after migration, the panel creates an “empty” default site.
• Reissue the TLS certificate (Let’s Encrypt likes it when A/AAAA is already pointing to the server and ports 80/443 are available).
• Restart the web server/container (Nginx/Apache). Make sure that the firewall/Cloudflare/other CDN sees origin.
• If you are using a CDN, clear the cache and check the proxying mode (the same “orange cloud” at Cloudflare).

Minimizing downtime.

• Zero Downtime plan:
  • Reduce TTL per day,
  • Raise the new server in parallel (blue-green),
  • Check the hosts file/direct IP,
  • Switch A/AAAA,
  • Keep the old origin in read-only mode for another 24-48 hours.
• Geodegradation: enable stale-if-error/”Always Online” in CDN so that users can see the cache in case of failures.
• Monitoring: set alerts (HTTP code, response time, certificate expiration date) — you will be the first to find out about the trouble.

Removing IP Or Domain Blocking

First, understand the type of lock.

• WAF/CDN (403, captcha): we look at the security logs: which rule is “firing” (bot traffic, frequency, country, signature).
• Provider/Routing (breaks on the highway): MTR/traceroute will show where the route collapses.
• Reputation lists and browser warnings: “dangerous site”, “malicious content”, Safe Browsing, etc.

Contacting providers and hosting companies.

• We are preparing the package: time, client IP, URL, response code, trace, screenshot of the block page, a copy of the WAF rules.
• We are writing to the hosting/CDN/provider support with a request to:
  • specify a specific rule/filter,
  • provide temporary mitigation (whitelist for your ASN/admin IP),
  • help to select the correct limits/GeoIP exceptions.
  • If the block is regulatory, follow the requirements of the law: sometimes the content is adjusted (removal of prohibited pages), then the block is removed.

Removal from blacklists. Google Safe Browsing / Search Console:

1. Confirm the domain in the Search Console,
2. In the “Security Issues” you will see a diagnosis (malicious code/phishing),
3. Clean the site (update CMS/plugins, delete shells),
4. Request a retest.
   • Spamhaus (SBL/XBL/PBL) and other reputation bases:
   • If the IP is banned, find the case page, fix the reason (virus mailing, open relays), attach the report and request a delist.
   • Remember: many of the lists are about email reputation. It is better for the site to switch to a different IP/ASN or hide the origin behind a CDN.
   • Other databases: PhishTank, OpenPhish, Yandex.Advisor/Webmaster, Microsoft Defender SmartScreen — their websites have complaint/recheck forms.

When it makes sense to change IP or hosting. Shared hosting: one “crazy” neighboring site, and the IP pool is under suspicion. Moving to a dedicated IP or other provider quickly changes the situation.

How to do it cleanly:

• Lower TTL,
• Order a new virtual server/hosting, check the IP for reputation before launching,
• Migrate the code/database,
• Update A/AAAA,
• Check for IPv4/IPv6 availability,
• Disconnect the old origin after 24-48 hours.
• Mail and reverse DNS: if you send emails from the same server, configure rDNS/SPF/DKIM/DMARC on the new IP (otherwise the emails will “fall” into spam).
• SEO: changing IP by itself does not affect positions, but monitoring uptime and speed after moving is mandatory.

Alternative Methods Site Unblocking For The Site Owner

CDN as a shield and “moving without moving”. What it does:

• hides the origin IP behind any cast grid,
• caches static and is able to return the “stale” cache in case of failures,
• puts WAF/Rate Limit/bot protection on the “edge” of the network,
• Routes traffic past congested nodes.
• How to bypass local blocks: if your IP is blocked, but not the domain, the proxying CDN usually “opens” the block.
• Close direct access to origin by IP (firewall with a list of IP CDN only), otherwise the locks will start to bypass.

Where it doesn’t help: if the block is based on the domain name/SNI or it is a legal ban on the resource itself, CDN is not a magic wand.

How to unblock a website with Mirrors and alternative domains.

While the main domain is in the block/under review, the mirror provides access. It works well with short instructions on social networks/mail and auto-forwarding for “unblocked” regions.
How to set up carefully:

• automatic synchronization (CI/CD, rsync, repository),
• in the on the mirror — to avoid duplicates in the search,
• Unified cache and header configuration,
• separate NS/registrars (reduces the risks of simultaneous blocking),
• clear status/access page with alternatives.
• After returning the main domain: gently divert traffic back (302 → 301), monitor logs, do not immediately cut the mirror to zero.

Multi-level access for different regions.

• GeoDNS/ Anycast/Traffic Manager: Direct users to the nearest operating region/cluster (Latency/Geo-based).
• Edge rules (edge rules/workers):
• for “problematic” countries, a simplified version of the site (fewer requests, without heavy third-party scripts),
• custom responses (for example, 451 with clarification) where access is legally prohibited,
• automatic rotation of alternative domains according to the list of available ones.
• Different providers by region: use multiple CDN/hosters (multi-CDN/multi-cloud) — if one provider is blocked locally, the traffic will go to another.

A mini-playbook, if “it’s turned off right now”:

1. Turn on the CDN proxy, close origin from direct access (allow-list IP CDN).
2. Lower the TTL and add an alternative domain on independent NS; raise the mirror (read/cache).
3. Post “how to open us” on communication channels (mail, social networks, status page).
4. At the same time, clean the site and run delist procedures in Safe Browsing/blacklists.
5. After removing restrictions— carefully return traffic by observing metrics and logs.

This way you not only fix the symptom here and now, but also build a stable architecture where the failure of one link does not turn the site into a “dark screen” for the entire audience.

How to Unblock a Website in Chrome: When “ERR_BLOCKED” Isn’t the End of the World

You open Chrome, enter a website address, press Enter, and instead of seeing the familiar page, you’re greeted with a dull gray message like “Access Denied,” “ERR_BLOCKED_BY_CLIENT,” or “This website has been blocked by your network administrator.”

At such moments, it feels like Chrome has suddenly become a parent with a belt, and you’re a teenager caught doing something forbidden. However, these are just barriers that can be overcome.

There are various reasons for blocking in Chrome:

1. Extensions and filters — AdBlock, antivirus, or corporate plugins sometimes mistakenly block websites.
2. Network restrictions — if you’re in an office, school, or connected to a filtered Wi-Fi network.
3. Regional blocks — the website may not be accessible from your country.
4. Browser settings — enabled “Safe Browsing” or manual rules in hosts.

The first thing to do is check if one of the extensions is “strangling” the site. Open the menu → “Additional Tools” → “Extensions” and temporarily disable anything that may block content. Sometimes the culprit is a harmless—looking plug-in to save traffic or protect against trackers.

If it’s a matter of network bans, Chrome is not omnipotent here — you will need to change the route of your traffic. A VPN or proxy is like putting on a fancy dress on the Internet: the server sees you already in another place. Chrome has a bunch of VPN extensions (one click), or you can install a separate app that will change the IP for the entire device.

For regional blocks, the recipe is the same — change the exit country. Even a free VPN can handle it, but paid services are more stable and faster. If you suspect Chrome itself, check the Settings → Privacy and Security. There you can disable “Safe Browsing” (but carefully, it weakens protection) and check if there are any extra restrictions in the “Site Settings” section.

In the worst-case scenario, you can do without Chrome — run the site in another browser or through the Incognito mode. Sometimes the filter works only in one profile, and in the other — everything is clean.

The main thing to remember: Chrome is not an iron lock, but just a door in which the keyhole is sometimes changed. And locks, as you know, are opened not only by keys, but also by other methods.
