The FBI and Homeland Security are currently investigating the significant outage of AT&T cell service that occurred earlier today. While a large portion of the network has been restored, national security spokesperson John Kirby has stated that efforts are underway to determine the cause of the outage.
Multiple federal agencies, including the FCC, Cisa, and the FBI, are involved in the investigation. Possible causes being considered include environmental factors such as weather, technical issues possibly related to an overnight upgrade, and the potential of a cyber attack.
