Having paid attention to this thread, im having issues with all pop3 communication to google mail severs for about the past 24 hours for another email account.  Noticed it when outlook started throwing send and receive errors before I went to sleep last night.

There are issues between Google and Comcast in the Denver area for at
least the last 12 hours. Pages are sporadically stalling before load
(indefinitely as far as I can tell). I found a gmail message I'd sent
more than 30 minutes prior still processing. This is affecting all
google services that I've tried so far.

However, I don't see any evidence this problem is DNS-related, and have
not otherwise been experiencing name resolution problems or had any
other recent Comcast connectivity issues.

So, if there's a clue-wielder from either company around, I'm happy to
provide traces and dumps if you want to ping me offlist.
