    这是一个创建于 2408 天前的主题,其中的信息可能已经有所发展或是发生改变。

    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

    @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

    @crb912 Chrome 应该是增加了好几个与域名解析相关的增强功能,你看看设置中的选项就知道了,都不用去看源码。

    我这边可以正常上,DNS 污染一般不会解析到 127.0.0.1
    通过 IPIP 查,国内 DNS 解析也都是正常的。

    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
