How to Circumvent Blocked Websites (Complete Guide)

By Jesse Lewis1/29/20265 min read

Access restrictions are increasingly common across the internet. Whether due to geo-blocking, firewalls, IP bans, DNS filtering, or government censorship, blocked websites impact individuals, businesses, researchers, and developers alike.

This complete guide covers how to circumvent blocked websites using a range of methods—from basic tools to enterprise-grade proxy solutions. You'll learn what causes access blocks, which strategies scale, and how to remain compliant while maintaining reliable access.

💡 Note: This guide is intended for accessing publicly available web content. Always follow local laws, organizational policies, and website terms of service.


Why Websites Get Blocked

Understanding the source of a block helps determine the best solution.

Common causes:

  • Geo-restrictions – Content limited by region or country
  • IP bans – Triggered by automation, scraping, or repeated access
  • Network firewalls – Enforced by schools, offices, or ISPs
  • DNS filtering – Blocking or redirecting via DNS resolution
  • Government censorship – Nation-level restrictions on access
  • Rate limiting – Throttling or blocking based on request volume

Each block type requires a different circumvention approach.


1. Exit Incognito Mode (Local Session Issues)

In rare cases, a blocked site may be the result of:

  • Corrupted cookies
  • Cached session data
  • Broken login states

Closing incognito or clearing your browser cache can resolve these local issues. However, this does not bypass real IP blocks or network restrictions.

For more on session behavior, see Managing Large Proxy Lists.


2. Change DNS Servers

DNS filtering is often used by ISPs or organizations to block access. Switching to public DNS can help bypass this.

Recommended DNS options:

  • Google DNS (8.8.8.8)
  • Cloudflare (1.1.1.1)
  • Quad9 (9.9.9.9)

Limitations:

  • Doesn’t work for IP-based or deep packet inspection blocks
  • Not suitable for automation or scraping use cases

3. Use a VPN

VPNs encrypt your traffic and route it through a remote server, masking your IP.

Ideal for:

  • ISP-level or public Wi-Fi restrictions
  • Private browsing and location spoofing

Not ideal for:

  • Scraping or automation (shared IPs are often blocked)
  • High-scale data access

To understand the tradeoffs, read Proxy vs VPN vs Tor.


4. Use Web-Based Proxies

These are browser-based proxy services used to quickly access a site.

Pros:

  • No installation needed
  • Useful for one-off browsing

Cons:

  • Unreliable and insecure
  • Blocked on most modern websites
  • Not usable for automation or repeated access

5. Use Proxies (Most Reliable Method)

For business, automation, and repeat access, proxies are the gold standard.

A proxy masks your real IP and forwards your requests through another server. This allows you to:

  • Bypass bans and geo-blocks
  • Rotate IPs to avoid detection
  • Run scraping and automation tools
  • Access restricted content reliably

Why Datacenter Proxies Work Best

Datacenter proxies offer the best performance-to-cost ratio for blocked website access.

With ProxiesThatWork's bulk datacenter proxies, you get:

  • High-speed IPs with low latency
  • Rotation support for bypassing rate limits
  • Scalable infrastructure for automation

Use cases include:


6. Rotate IP Addresses

Static IP usage can still lead to blocks. Rotation is key to resilience.

Rotation strategies:

  • Time-based (rotate after X minutes)
  • Request-based (rotate per call)
  • Session-based (rotate per browser session)

7. Change Browser Fingerprints

Some blocks are triggered by non-IP factors such as fingerprinting.

Fingerprint data includes:

  • Browser type and user agent
  • Language and timezone
  • Installed fonts and extensions

For stealth browsing, use anti-detection tools (and see Anti-Detection Browser Comparison).


8. Use the Tor Network (Not for Scale)

Tor anonymizes your traffic through layered relays.

Pros:

  • High anonymity

Cons:

  • Very slow
  • Blocked on many websites
  • Unfit for scraping, automation, or enterprise needs

Method Comparison Table

Method Bypasses IP Blocks Scalable Automation-Ready
Incognito Mode No No No
DNS Change Limited No No
VPN Sometimes No No
Web Proxy Sometimes No No
Tor Yes No No
Datacenter Proxies Yes Yes Yes

Best Practices to Avoid Detection

  • Diagnose the type of restriction first
  • Use fresh, clean IPs
  • Rotate requests and session data
  • Monitor for block signals (errors, captchas, redirects)
  • Respect target site behavior and response limits

Using proxies and circumvention methods must be done responsibly:

  • Access only publicly available data
  • Comply with all applicable laws and terms of service
  • Avoid scraping private or restricted content

Final Thoughts

Simple DNS changes or VPNs can work for casual restrictions, but for consistent, scalable access to blocked content, proxies are the most reliable choice.

ProxiesThatWork offers affordable, high-performance bulk datacenter proxies built for web scraping, monitoring, and automation.

Used correctly, proxies offer a responsible, scalable way to access the open web—without reliance on fragile tools or risky tactics.
