I had the same issue during that time frame, but a completely different behavior. The server simply didn't answer queries related to my car, as if the car was out of 3G range. I did not receive any authentication errors or anything. The mobile app showed "Contacting car..." yet the car was happily playing Slacker, CC on, etc.
That seems consistent with what should happen when the Tesla authentication system is down, but the 3G internet connectivity to the car is still working. Egress traffic (from the car to the internet) would be unaffected, but ingress traffic (from Tesla to the car) would not work because the necessary tokens are unavailable after the 15 minute automatic expiry window has passed.
