AT&T has said that a massive outage that left people unable to make calls – including to 911 – was not caused by a cyber attack.

The provider said thew outage was caused by “the application and execution of an incorrect process” during network expansion. “We are continuing our assessment of today’s outage to ensure we keep delivering the service that our customers deserve,” the statement read.

The White House echoed this saying that there was no evidence the outage was caused by a cyber attack

According to CNN, John Kirby, a National Security spokesman, said the Department of Homeland Security and the FBI are looking into the Thursday incident and contacting partners to “see what we can do from a federal perspective to lend a hand to their investigative efforts to figure out what happened there.”

Still, he said, officials are unsure about what caused the widespread outage.

“The bottom line is we don’t have all the answers to that. I mean, this just happened earlier today. And so we’re working very hard to see if we can get to the ground truth of exactly what happened.”

Cybersecurity and Infrastructure Security Agency (CISA) is now working with AT&T to get to the root of the issue.

“CISA is aware of the reports and we are working closely with AT&T to understand the cause of the outage and its impacts, and stand ready to offer any assistance needed,” the agency’s Executive Assistant Director for Cybersecurity, Eric Goldstein, said in a statement.

The outage, which began early on Thursday, led to warnings from emergency services and advice from companies to get around the issue.

AT&T has around 250 million customers, making it the US’s biggest phone network by some distance. The company said all its entire network had been restored around 3pm ET.

Customers compare situation to Leave The World Behind

It’s only a few months since the release of Leave The World Behind, Netflix’s film with a tag line that does feel a little familiar today:

Of course, there is internet, and most phones are still working. But it is a reminder that such an outage is possible.

AT&T referred customers to ‘network update’ page

AT&T pointed affected customers to a special page on its website during the outage. It’s not very detailed:

“Some of our customers are experiencing wireless service interruptions this morning. Our network teams took immediate action and so far three-quarters of our network has been restored. We are working as quickly as possible to restore service to remaining customers.”

WiFi calling isn’t the only way to avoid the phone network

On Thursday, AT&T recommended that affected users get onto WiFi and use that to call people. (Instructions are below.)

But there are plenty of other ways of communicating without a phone connection, too.

You can download maps offline, for instance (Google has long allowed this, and Apple Maps has recently introduced it, too). And you can download music and videos onto your phone ready for any long journeys.

National Association of Broadcasters advocates on the importance of AM radio amid outages

“Today’s cell service outage is another example of the critical need to keep AM radio in cars,” the association said in a statement posted to X, formerly Twitter. “When the internet is out, power lines are down and cellphones can’t find a signal, AM radio is there, providing reliable life-saving alerts & updates.”
