Comcast DNS

Add Seattle/Washington to the list.

It's been a rough week with Comcast, with a state-wide outage last
Thursday morning as well.

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.
