This article will show you how to block and suggest other things to do.

As a result, pages will load faster, and users won’t have trouble navigating the web.

What are the reasons for blocking

Although offers advantages, there are scenarios where blocking it might be necessary. Some of the reasons for blocking include the following:

  • Privacy Concerns: You may be concerned about the data collected or tracked by, which could compromise your online privacy.
  • Access Restrictions: Certain websites or applications that rely heavily on might not function properly due to geographical restrictions or network limitations. Blocking can help bypass such issues.
  • Reducing Bandwidth Usage: If you’re on a limited bandwidth plan or have bandwidth constraints, blocking can help conserve your data usage.

How to Block

Depending on your requirements and technical expertise, you can use several methods to block Here are a few practical approaches:

Method 1: Using Hosts File to Block

The host file is a configuration file specific to your machine that translates domain names into IP addresses. The host file allows you to block or reroute traffic for the IP address Follow these steps:

  • You can open the host file on your computer. On Windows, it is typically located at C:\Windows\System32\drivers\etc\hosts, while on macOS and Linux, you can find it at /etc/hosts.
  • After that, open the file using a text editor with administrator privileges.
  • Add the following line at the end of the file:
  • This will redirect all requests for to the local IP address (localhost), effectively blocking it.
  • Save the changes and close the file.
  • Clear your DNS cache to ensure the new configuration takes effect. You can do this by opening the command prompt (Windows) or terminal (macOS/Linux) and entering the appropriate command:

Windows: ipconfig /flushdns

macOS/Linux: sudo killall -HUP mDNSResponder

  • should now be restricted if you’ve followed these steps.

Method 2: Using Browser Extensions to Block CDN

If you prefer a solution that operates at the browser level, you can use browser extensions to block Many popular browsers offer extensions designed explicitly to block unwanted content. Here’s how you can use a browser extension to block

  • Open your browser and navigate to the extensions/add-ons store.
  • Search for an ad-blocking or content-blocking extension that suits your browser. Popular options include uBlock Origin, AdBlock Plus, and Privacy Badger.
  • Install the extension by following the instructions provided for your specific browser.
  • Once installed, access the extension’s settings and add to the list of blocked domains or customize the filters to block content from this domain.
  • Save the settings and restart your browser if necessary.
  • The browser extension should now block and prevent any associated content from loading.

Method 3: Using Firewall Rules to Block CDN

For more advanced users or those with access to network-level configurations, firewall rules can effectively block for multiple devices on a network. This method is beneficial if you want to block across all devices connected to your network. Here’s a general overview of the process:

  • Access your router’s administration interface. This is usually done by entering the router’s IP address into a web browser.
  • Navigate to the firewall or access control settings.
  • Create a new rule to block outbound traffic to The exact steps will vary depending on your router’s interface and firmware.
  • Save the firewall rule and apply the changes.
  • Restart your devices or renew their network connections to ensure the new firewall rule takes effect.

Using firewall rules requires technical knowledge and may differ based on your router and network setup. Refer to your router’s documentation or seek assistance from a network professional if needed.

Considerations When Blocking

Before blocking, it’s essential to consider a few things:

  • Impact on Website/App Functionality: Blocking may impact the functionality or performance of websites or applications that rely on it. Ensure that blocking it won’t cause any undesired consequences.
  • Regular Updates: CDN providers may use multiple domain names or IP addresses, so blocking might not entirely prevent access to their content. Regularly check for updates and adjust your blocking methods accordingly.
  • Browser Compatibility: Browser extensions for blocking might not be available for all browsers or versions. Ensure that the extension you choose is compatible with your browser.

Alternatives to Blocking

If outright blocking of is not desirable or feasible, consider these alternative options:

  • Network-Level Filtering: Configure your network to selectively filter or limit access to This can be done using content filtering solutions or network proxies.
  • Privacy Measures: Explore privacy-enhancing browser extensions or tools that can help minimize data collection and tracking associated with
  • Contact Website Administrators: If you’re experiencing specific issues with a website or application related to, contact the website administrators or support teams to resolve the issue.


Blocking can be a viable option to address privacy concerns, access restrictions, or bandwidth limitations. Modifying the host’s file, utilizing browser extensions, or implementing firewall rules can effectively block according to your needs. However, be mindful of the potential impact on website functionality and consider alternative approaches if outright blocking is not ideal. Remember to stay informed about updates and adjust your blocking methods accordingly.


Q1. Can I block on mobile devices?

  • Yes, you can block on mobile devices by using browser extensions that support mobile browsers or by configuring DNS settings on your mobile device.

Q2. Will blocking improve my internet speed?

  • Blocking may not directly improve your internet speed. It primarily helps with blocking access to specific content delivered through that CDN.

Q3. Is it legal to block

  • Blocking is generally within your rights as a user. However, it’s important to review any terms of service or agreements you have with websites or applications that utilize, as they may have specific guidelines or restrictions.

Q4. Can I unblock if needed?

  • If you have blocked using the methods mentioned in this article, you can reverse the changes to unblock it. Remove the relevant entries from the host’s file, disable the blocking browser extension, or modify the firewall rules accordingly.

Q5. Are there any risks associated with blocking

  • While blocking can address specific concerns, it may also result in unintended consequences. Ensure that blocking this CDN does not negatively affect the functionality or performance of websites or applications you rely on.
