Why websites get blocked and what you can do about it

A website can be blocked at several different points between you and the site itself. Your workplace, school, or home network might block it. Your internet service provider might block it. Your country's government might block it. The blocking method matters because different blocks require different approaches — and some approaches won't work on some blocks.

Before you try anything, understand what's actually blocked. If you're on a work or school network, the block is usually intentional and you should check your acceptable use policy first. If you're trying to reach a site that's blocked by your ISP or government, the technical options are different. This guide covers the main methods people use and what each one actually does.

Key Takeaways

  • Network blocks (workplace, school, home) usually filter traffic at the router level and can often be bypassed with a VPN or proxy, but doing so may violate your acceptable use policy.
  • A VPN encrypts your traffic and routes it through another server, hiding what sites you visit from your network — but it slows your connection and some networks block VPN traffic itself.
  • A proxy server acts as a middleman between you and the blocked site, but it's less secure than a VPN and many workplaces block known proxy services.
  • DNS-level blocks can sometimes be bypassed by changing your DNS provider, but this only works if your network doesn't force its own DNS.
  • If a site is blocked by your government or ISP at a deeper level, technical workarounds become much harder and may carry legal risk depending on where you live.

Using a VPN to bypass network blocks

A VPN (virtual private network) encrypts all your internet traffic and routes it through a server in another location. From your network's perspective, you're just sending encrypted data to the VPN company — the network can't see which websites you're actually visiting. This works well against network-level blocks at workplaces, schools, and homes.

To use a VPN, download a VPN application (common ones include ProtonVPN, Mullvad, and NordVPN), install it, create an account, and turn it on before you open your browser. Once it's running, your traffic goes through the VPN's server first, so the blocked site sees the VPN's address instead of yours. The downside is that VPN traffic is slower than direct traffic, and some networks actively block known VPN services — you may need to try a few different VPN providers to find one that works on your specific network.

Important: using a VPN on a work or school network may violate your acceptable use agreement, even if the technical block can be bypassed. Check your policy before you try this.

Using a proxy server

A proxy server sits between you and the website you want to reach. Instead of connecting directly to the blocked site, you connect to the proxy, and the proxy connects to the site on your behalf. From your network's perspective, you're only talking to the proxy server, not the blocked site.

You can use a web-based proxy by visiting a proxy website (search for "free web proxy") and entering the blocked site's address into the form. The proxy then loads the site and shows it to you. This is simpler than a VPN because you don't need to install anything, but it's also less secure — the proxy can see your traffic — and many workplaces block known proxy services by URL.

Browser extensions that act as proxies exist, but they work the same way: they route your traffic through a third-party server. The main advantage over a web proxy is convenience; the main disadvantage is that you're trusting the extension maker with your browsing data.

Changing your DNS provider

Some networks block sites by intercepting DNS requests — the lookup that translates a website name (like google.com) into an IP address. If your network does this, you can sometimes bypass it by changing which DNS server your device uses.

Common alternative DNS providers include Cloudflare (1.1.1.1), Google (8.8.8.8), and Quad9 (9.9.9.9). On Windows, go to Settings > Network & Internet > Change Adapter Options, right-click your connection, select Properties, find IPv4 Properties, and manually enter the new DNS server address. On Mac, go to System Preferences > Network, select your connection, click Advanced, go to the DNS tab, and add the new server. On your phone, the process varies by device but usually involves going to Wi-Fi settings and editing the DNS under Advanced options.

This only works if your network doesn't force its own DNS — many corporate and school networks do. If you change your DNS and the site still doesn't load, the block is happening at a different level and you'll need to try a VPN or proxy instead.

Understanding blocks you probably can't bypass

If a website is blocked by your internet service provider or by your country's government, the block happens at a much deeper level than a network filter. These blocks often use multiple methods at once — DNS blocking, IP blocking, and deep packet inspection — and bypassing them is much harder.

A VPN can still work against ISP and government blocks because the VPN encrypts your traffic so deeply that the ISP or government can't see which site you're trying to reach. However, some countries actively block VPN traffic itself, and using a VPN to bypass government censorship may be illegal depending on where you live. Before you try this, research the laws in your location. In some countries, circumventing censorship carries serious legal consequences.

What to do if nothing works

If you've tried a VPN and a proxy and the site is still blocked, the block is probably happening at multiple levels or your network is actively blocking the tools you're using. At this point, you have a few options: use a different network (a phone hotspot, a library, a coffee shop), contact your network administrator and ask them to unblock the site, or accept that the block is intentional and respect it.

If you're on a work or school network, the block is almost certainly intentional. Trying harder to bypass it could get you in trouble. If you need access to the site for legitimate work or school reasons, ask your IT department or network administrator directly — they may be able to whitelist it for you.

Frequently Asked Questions

Is using a VPN illegal?

In most countries, no — VPNs are legal and widely used for privacy. However, some countries restrict or ban VPN use, and using a VPN to bypass government censorship may be illegal in those places. Check your local laws before you use one. Using a VPN to bypass a work or school network block may violate your acceptable use policy even if it's not illegal.

Will my network administrator know if I use a VPN?

They'll see that you're sending encrypted traffic to a VPN server, but they won't see which sites you visit. However, the fact that you're using a VPN at all may be visible, and some networks block VPN traffic entirely. If your network is actively monitoring for VPN use, they may be able to tell you're using one.

Can I use a mobile hotspot to bypass a network block?

Yes. If you're on a blocked Wi-Fi network, switching to your phone's mobile hotspot uses a different network entirely, so the block doesn't apply. This works for workplace and school networks but not for ISP-level or government-level blocks, which affect all your traffic regardless of which network you use.

What's the difference between a VPN and a proxy?

A VPN encrypts all your device's traffic and is more secure, but it's slower and some networks block it. A proxy only handles specific traffic (usually just your browser) and is faster, but it's less secure and easier for networks to block. For most people trying to bypass a network block, a VPN is the better choice.

Why would a website be blocked by my ISP?

ISPs sometimes block sites at the request of copyright holders, to comply with court orders, or to filter content they consider harmful. The reasons vary by country and ISP. If you believe a site is blocked by mistake, contact your ISP and ask them to review it.
