Zettlr也發布於github:https://github.com/Zettlr/Zettlr和https://zettlr.com/
下載鏈接都定向到<github-production-release-asset-2e65be.s3.amazonaws.com>！沒有速度！
修改hosts
試着如下的修改hosts，好像也沒有作用！用laod的hosts，仍然沒有速度！不知道哪個地方出問題了？
多個地點 ping 檢測：http://ping.chinaz.com/github-production-release-asset-2e65be.s3.amazonaws.com
找到響應速度比較小的，編輯hosts文件，添加如下內容
52.216.146.179 github-production-release-asset-2e65be.s3.amazonaws.com
