邮箱收到了 issue 通知本打算开 github 瞅一眼结果打不开？？？ chrome 提示拒绝连接，嗯，熟悉的 DNS 污染感觉 赶紧 dig 一手，可怕了...直接解析到本地...8.8.8.8 也不行... 而且包括其 cdn 也被污染，奇怪的是 不用 chrome 访问直接 dig 就是正确地址 真是奇怪...
以下是 dig 日志

 | 6 zw 2018-04-21 15:39:31 +08:00 我昨天发过一贴，t/448197，最近 Chrome 的域名解析不知是啥缘故，感觉不太正常。。。 |
 | 7 crb912 2018-04-21 19:32:57 +08:00 via Android @zw 域名解析不是 chrome 负责的吧，chrome 只是浏览器。域名解析是有 IPS 服务器负责 |

| 14 input2output 2018-04-21 19:52:56 +08:00 @peterpei #11 我不知道... 我不翻墙,允许缓存大约 1s 加载完毕  |
 | 15 PaperCUbe 2018-04-22 11:05:04 +08:00 同青岛移动。我还特地问了一下身边的联通用户，他们表示都正常。移动无论是宽带还是数据网络都是一样，解析到 127.0.0.1 并且访问被拒绝。目前正在勉强改 hosts 度日 |
