FAQ

Q: The github webpage cannot be opened?

[GitHub cannot be loaded] GitHub cannot be loaded, and the webpage is garbled when opened - Obtain the GitHub official CDN address, modify the system Hosts file and refresh the cache

When using Google Chrome browser and Sogou browser to access the github.com website, the web page cannot be opened, which eliminates the problem of the browser.

github.comThere are many IP addresses corresponding to this domain name, some of which are within the scope of access allowed in our country, and some of which are not. When the corresponding address resolved by your computer through DNS github.comhappens to be within the range of access allowed in our country, you can access it, but not vice versa.

Under normal circumstances, if you refresh the browser a few times and resolve the DNS a few more times, you may be able to open github normally. But before long, the same problem will appear again. The solution is to simply resolve the accessed github.comIP address to a domestically accessible IP address.

Get the official DSN address of github

Open IPADDRESS.COM and search in the upper right corner to find the following three DNS addresses:

http://github.com 
http://assets-cdn.github.com http://github.global.ssl.fastly.net

http://github.com

Modify the system hosts file

The location of the hosts file varies on each system. Details are as follows:

Windows system: C:\Windows\System32\drivers\etc\hosts ;
Linux system: /etc/hosts;
Mac (Apple Computer) system: /etc/hosts;
Android (Android) system: /system/etc/hosts;
iPhone (iOS) system: /etc/hosts.

At the end of the hosts file, add dns content:

140.82.113.4 github.com

185.199.108.153 assets-cdn.github.com 
185.199.109.153 assets-cdn.github.com 
185.199.110.153 assets-cdn.github.com 
185.199.111.153 assets-cdn.github.com 

151.101.1.194 github.global.ssl.fastly.net 
151.101.65.194 github.global.ssl.fastly.net 
151.101.129.194 github.global.ssl.fastly.net 
151.101.193.194 github.global.ssl.fastly.net

If the hosts file does not have modification permissions, modify the permissions.After modification, remember to change the permissions back。

Right-click the hosts file->Properties->Security->Edit->Select Users in the group or user name field->Write

Flush dns cache

ipconfig /flushdns
