"Unraveling the AT&T Network Outage: Causes and Consequences"

AT&T's major wireless outage was caused by a botched network expansion update, not a cyber attack, leading to disruptions for many mobile customers. The outage, which began early in the morning, affected over 70,000 customers and prompted an investigation by the FCC and other agencies. AT&T stated that three-quarters of the network was restored by midday and full service was restored by the afternoon. The company attributed the outage to an "incorrect process" during the network expansion, while the FCC and other agencies confirmed that it was not caused by cyber-attackers.
