Reports that most of Tennessee is without 9-1-1 service right now: https://www.dslreports.com/forum/r32982150-AT-T-Suffers-outa... And AT&T mobile is down across Kentucky: https://www.dslreports.com/forum/r32981927-Services-Suspicio... Also reports above that calls into Tennessee aren't working.
It is pretty nuts that a single physical location can bring down a state's worth of 911, and cellular. It is either institutional incompetence, or malice, or laziness.
Same issue with internet peering in quite a few cities (no viable 2nd location, costs a lot of money to double up the gear, additona optical transport).
