修改hosts文件

TeXstudio发布于github:https://github.com/texstudio-org/texstudio/releases
Zettlr也发布于github:https://github.com/Zettlr/Zettlr和https://zettlr.com/

下载链接都定向到<github-production-release-asset-2e65be.s3.amazonaws.com>！没有速度！

修改hosts

试着如下的修改hosts，好像也没有作用！用laod的hosts，仍然没有速度！不知道哪个地方出问题了？

多个地点 ping 检测：http://ping.chinaz.com/github-production-release-asset-2e65be.s3.amazonaws.com

找到响应速度比较小的，编辑hosts文件，添加如下内容

52.216.146.179  github-production-release-asset-2e65be.s3.amazonaws.com
52.216.97.171  github-production-release-asset-2e65be.s3.amazonaws.com
52.216.176.115  github-production-release-asset-2e65be.s3.amazonaws.com
52.216.130.131  github-production-release-asset-2e65be.s3.amazonaws.com
52.216.108.11  github-production-release-asset-2e65be.s3.amazonaws.com

hosts文件：
Windows 7 位于：C:WindowsSystem32driversetc
