Sorry to raise an old thread, but it looks like Comcast Broadband got his with this in chicago last night. I'm a home user so it's impossibe to get any real information from tech support. Our DNS servers went down, but everything else was fine. I was able to resolve 2 addresses, a google search, and then a regular website I visit, but the speed was comparable to an old 14.4 modem. It appears that they were having some real big problems. My first call to them gave me an automatic message saying that there was a service interruption and that their call center was slammed. I called again and actually got someone (in less time then when there isn't a service interruption...quite odd) but they said that all of their DNS servers were down. I asked them if they knew any public ones for me to connect to, or backups, and dude said "If there are, they're down too" "You can surf by IP address though" at this point i thanked them for their lack of foresight in not even having a public backup of some kind. I phoned a buddy of mine and got a public DNS server and it managed to work, but i was experiencing an incredible amount of lag. I chocked it up to travel time in the resolving of the names, but it didn't seem right. Anyhoo, all's back to normal, but I can't help but think that Comcast got popped by this last night.
