访问GitHub太慢怎么解决？

科学上网不是全局模式下的情况

方法一：将下面这些 添加到PAC规则里

.github.com
||github.com
github.global.ssl.fastly.net
.githubassets.com
||githubassets.com
.githubusercontent.com
||githubusercontent.com

这样 就可以 秒开 GitHub 了

方法二 修改host文件

通过ip查询工具获取 域名真正的ip
示例：140.82.114.4 github.com
以下这段

#GitHub Start
140.82.113.4 github.com
199.232.69.194 github.global.ssl.fastly.net
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
140.82.112.3 github.com
140.82.114.4 gist.github.com
185.199.108.153 assets-cdn.github.com
185.199.108.133 raw.githubusercontent.com
185.199.108.133 gist.githubusercontent.com
185.199.108.133 cloud.githubusercontent.com
185.199.108.133 camo.githubusercontent.com
185.199.108.133 avatars.githubusercontent.com 
185.199.108.133 avatars0.githubusercontent.com
185.199.108.133 avatars1.githubusercontent.com
185.199.108.133 avatars2.githubusercontent.com
185.199.108.133 avatars3.githubusercontent.com
185.199.108.133 avatars4.githubusercontent.com
185.199.108.133 avatars5.githubusercontent.com
185.199.108.133 avatars6.githubusercontent.com
185.199.108.133 avatars7.githubusercontent.com
185.199.108.133 avatars8.githubusercontent.com
#GitHub End

或者 第二段

#GitHub Start
140.82.113.4 github.com
140.82.112.4 github.com
140.82.112.3 github.com
199.232.69.194 github.global.ssl.fastly.net

方法三 更换dns

使用公共dns代替 宽带运营商自带dns
阿里云公共DNS 223.5.5.5
DNSPod 119.29.29.29
国外 1.1.1.1

方法四 自定义域名的解析记录

以 DNSPod的公共解析为例
通过IPAddress.com网站 查询出下列三个网址的对应ip地址
github.com ，assets-cdn.github.com ， github.global.ssl.fastly.net
然后 在控制台 配置 自定义 解析
