I'm posting this here since I'm aware ComCast holds the cable here in the midwest (TimeWarner held it in the region I'm previously from, ie: you can't get ComCast internet there, it doesn't exist) and I'm aware for ComCast's DNS server issues. In other words, no your "internet" isn't down.. the DNS server is for the most part - think of it as a phone book and you just lost your link to directory assistance. It translates the words for websites, into the "phone number" or IP Address, you type
www.lostjeeps.com and it returns the IP. The system works great, when it works, confuses and frustrates people when it doesn't.
Here's the directions to "Fix" or bypass ComCast's unstable DNS Services, it will not affect any of your home network security settings, it's free, and stable - and there is a local server located in Chicago operated by NeuStar.
