Thursday morning saw widespread network outages across the nation for AT&T, with both cellular service and internet connectivity affected, as reported by the monitoring site Downdetector.

While some Verizon and T-Mobile users also encountered disruptions, these were primarily individuals attempting to reach AT&T subscribers.

Customer reports indicated over 32,000 AT&T outages around 4 a.m. ET, spiking to more than 50,000 by 7 a.m. ET, with the highest concentration of issues reported in Houston, Chicago, Dallas, Los Angeles, and Atlanta.

By just before 8 a.m. ET, the number of reported AT&T outages surged to over 71,000. Meanwhile, T-Mobile experienced slightly over 1,100 outages, and Verizon reported around 3,000 outages as of 7 a.m. Thursday.

The cause of this service disruption remains unclear.

AT&T addressed the matter Thursday morning, stating, “Some of our customers are experiencing wireless service interruptions this morning. We are working urgently to restore service to them. We encourage the use of Wi-Fi calling until service is restored.”

On X, the company has been actively engaging with customers experiencing cell service issues nationwide.

Verizon clarified that their network itself was not affected by the outages; rather, it was impacting customers attempting to connect to another carrier.
