A few days ago, I noticed some issue with my internet connection. Some pages weren't loading all the way, and some connections needed to be restarted several times before they would resolve. I assumed that my connections were just being dropped due to a particularly busy load on my ISP's end (I use Comcast). Today, I started up Chrome, and I saw this message:
The server's security certificate is revoked! You attempted to reach www.google.com, but the certificate that the server presented has been revoked by its issuer. This means that the security credentials the server presented absolutely should not be trusted. You may be communicating with an attacker. You cannot proceed because the website operator has requested heightened security for this domain.
Thinking it could be an extension messing it up, I uninstalled Chrome and tried using Chromium instead, with the same result. This was very worrying for me, so I started some other computers at my house, and was able to replicate the issue (but not at the same time; each one displayed the message at one point but when one displayed it, the others didn't) on them, so I know it's not malware on my end.
None of the other browsers which I tried (Opera, Firefox, and IE) had this issue, but they all seemed to drop a lot of connections. Is there anything I can do to fix this, or is is solely an ISP problem?
