FBI and Homeland Security are looking into the AT&T cellular outage, White House says

A sudden cellular outage left tens of thousands of AT&T customers without service on Thursday — and the feds are looking into it.

While AT&T restored all of its networks by 3 p.m. ET, White House spokesperson John Kirby said that the FBI and Department of Homeland Security are looking into the cellular outage.

“The bottom line is we don’t have all the answers,” Kirby told reporters on Thursday, according to Reuters.

AT&T later said the outage was caused by a software update. In a Thursday afternoon statement, the company confirmed the outage was not a cyberattack.

“Based on our initial review, we believe that today’s outage was caused by the application and execution of an incorrect process used as we were expanding our network, not a cyber attack,” the statement said. “We are continuing our assessment of today’s outage to ensure we keep delivering the service that our customers deserve.”
