I went to turn on the A/C using the Tesla app and it reported it was waking my car. That's unusual, as I have the "stay connected" option selected, and I was in an area with coverage. The app was never able to connect. Got to the car and google maps wouldn't update and slacker wasn't working. UI said I was in 3G (also odd). I rebooted. After a long while, the car reconnected with LTE. Google maps and slacker still wouldn't work. I then turned on my verizon hotspot and connected the car. Everything started working right away. A google search reveals a few articles about AT&T having problems two days ago (8/13). I haven't seen anything for today -- yet. Andrew Note to mods: I couldn't figure out where to place this thread. It's not Model S or X specific, it's not about Tesla Motors, etc. I think several of the S and X areas could be combined into one. The UI is 99% the same between the two cars.
