chrome 在 linux 下今天爆发, 绝大多数 https 访问不了.

今天周一, 回公司后打开邮箱发现thunderbird和iceweasel(firefox)下web版的outlook都访问不了. 于是发邮件个Technical support group,

当时报错如下
===我是错误的分割线 Start========
Secure Connection Failed

An error occurred during a connection to cdcmail.synnex.com. Peer's Certificate has been revoked. (Error code: sec_error_revoked_certificate)

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

===我是错误的分割线 End=========

TSG让我等会儿重试下. 几分钟后重试可以收发了, 不过速度下降了.
接下来, 大约半个小时后, 我有需要连github, 发现连不上了

https://ruby-china.org https://github.com 都连不上了.
点开github
报错

Your connection is not private

Attackers might be trying to steal your information from github.com (for example, passwords, messages, or credit cards).

ReloadHide advanced
github.com normally uses encryption to protect your information. When Chrome tried to connect to github.com this time, the website sent back unusual and incorrect credentials. Either an attacker is trying to pretend to be github.com, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Chrome stopped the connection before any data was exchanged.

You cannot visit github.com right now because the website uses HSTS. Network errors and attacks are usually temporary, so this page will probably work later.

NET::ERR_CERT_AUTHORITY_INVALID

点开证书一看, 机构不是Digi那个. firefox下可以正常访问, 我加了例外. 但是chrome就是不让加例外. 怎么办呢? 有人知道这个chrome的证书流程吗
