"Walked outside with my notebook and hooked up to a neighbors WiFi (I set it up for her) which is fed by Qwest DSL and not Comcast, and it was fine."
I've been having similar problems lately like Screw Joob getting ahead of itself and pausing, pages loading slow and the like but I chalked it up to server traffic not thinking it may be Cumcast. Then it died around 1:00am today so I gave up and went to bed figuring I'd deal with it later. On a whim I tried the connection when I got up and found it OK, everything appeared normal so I ran their "employees only" test and found my connection speed had doubled from what it was before the mess even started. Like the ads say "your actual mileage may vary" but in my case Comcast is the most reliable service I ever had but it seems it took a complete failure for them to notice the problem. (?)

I don't know about you but I think he leans more toward A Doobie and Flesh Gordon.
