add me to the list. the launcher window opens, but the screen doesn't populate any info, it just stays white :/ I did see much earlier today that there was going to be some sort of maintenance for twenty minutes, but I don't remember when they were going to do it.
I have U-verse as well. Normally when I have problems staying connected, I've found that resetting the residential gateway (by pulling power briefly) takes care of it. Not this time, though - I'm just as flummoxed by this as anyone else.
Wish I could say how many were affected, but I could not get into LOTRO, STO or Champions. Got into SWTOR. There were several threads about similar issues on the LOTRO forums. The only thing that everyone had in common was AT&T. Friends that had other service providers were not having issues.
