It's AT&T's DNS servers. So I changed them on 2 of my devices and they work now. I'm not going to change my other 8 devices for now. I may get a different router so I can use my own DNS servers instead of being forced to use AT&T ones. Hopefully they will sort it out soon, if their DNS servers are baked, could be that TV is affected too. I don't have U-Verse TV.
I was about to suggest that! Primary 188.8.131.52 and secondary 184.108.40.206 (Google). Maybe do a tracert to a problem site to see where it breaks.
By the way... I'm on ATT's DNS servers right now, and can get to all the sites listed in the thread. I am also on the other coast though.
