ATT U-Verse is down

Greenville, SC says I don't have service when trying to log into the ATT U-Verse mobile app. Tried to activate my Showtime Anytime on my Roku and that app says I don't have a subscription after I log into my ATT U-Verse account. I have service though. Tried several times and a few times it gave me a different error message saying the ATT back end servers were down. Which is it? Server is down or I don't have service? I have service and I do subscribe to Showtime but I can't watch it on my Roku because I can't login. Very annoying. Please fix the issue!
