I had AT&T DSL internet service. I was happy. I recommended it to my friends. Then AT&T, over a period of a few months, cut the speed to dial-up levels. Dial-up. YouTube wouldn't load. Hulu was the same. And forget about downloading anything--it would take forever.
And there was, apparently, no recourse. None. Even after many hours on the phone, and in spite of paying more for the highest tier of service, I was getting shit!

This was the best AT&T U-verse could do:
AT&T U-verse was giving me less than 1Mbps. Sad.
And today I got the Comcast "Performance Boost" installed:
24Mbps!? Wow! Happy now! :-)
