github 被 DNS 污染？

刚刚想往 github 上传点修改，发现提示ssh_exchange_identification: Connection closed by remote host错误

又试了试 git remote show origin命令和ssh -T git@github.com 发现还是一样的错误。

于是 dig 了一下 github.com ，结果神奇的发现了下面的信息， github 这个域名竟然被解析成了 1.1.1.1 ，我了个擦擦啊。。还让不让人活了。

; <<>> DiG 9.9.5-3ubuntu0.8-Ubuntu <<>> github.com

然后用 114 测试了一下，发现直接查不到。。

→ dig github.com @114.114.114.114
