Github访问慢解决办法

原因

为什么慢？github的CDN被某墙屏了。

解决方法

绕过dns解析，在本地直接绑定host，该方法也可加速其他因为CDN被屏蔽导致访问慢的网站。

实现

在本地host文件中添加映射，步骤如下：

1. 用文本编辑器打开hosts文件，位于C:\Windows\System32\drivers\etc目录下
2. 打开 http://tool.chinaz.com/dns ,这是一个查询域名映射关系的工具
3. 查询 github.global.ssl.fastly.net 和 assets-cdn.github.com 两个地址
4. 多查几次，选择一个稳定，延迟较低的 ip 按如下方式添加到host文件
5. 保存文件，重新打开浏览器，起飞。

#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.
#   127.0.0.1       localhost
#   ::1             localhost
