2024 outage

On February 22, 2024, cellular service was disrupted across the United States with "millions" unable to connect to the cellular network. Municipalities reported that AT&T customers were unable to place calls to emergency services, even when using their phone's SOS capability. The blackout prompted the FBI and Department of Homeland Security to launch investigations into the possibility of a cyber attack being the cause of the blackout. AT&T however later claimed that the cause was instead a poorly timed server update. Users were later compensated credit as a result of the outage. In March, the FCC opened an investigation into the outage.
