I’m on AT&T for cell service. Live in one of the red zones, currently visiting family in another. Last night, I couldn’t call my wife across the house, immediate Call Failed error. Couldn’t call a buddy back home, same error. Internet comms are working fine (iMessage and Facetime) using WiFi on a non-AT&T Internet provider. AT&T Internet back home seems fine, I can get a camera feed at the house from here. But cellular, at least last night, was really messed over.
Another buddy who is a very senior AT&T engineer for another area confirms things are really screwed in Nashville, said it would take years to get everything back right. He might get sucked into the repairs, probably will.
This one bears watching.
