Customer support also down nationwide.
Here is a news story about outage:
AT&T U-Verse Service Suffers Massive, Nationwide Outage
I got thought to at&t wireless customer service, who explained: unknown causes. Home, internet, tv all affected. All Uverse customer support affected and calls will not go through. Unknown amount of time before problem fixed.
Remember to call in for your credit for lost services tomorrow ( if it's fixed by then)
