FBI, Department of Homeland Security investigating AT&T outages

Several agencies, including the FBI and Department of Homeland Security, are investigating whether the widespread AT&T outages are the result of a cyberattack or hack.

Reports of disruptions started flooding in early Thursday morning around 4 a.m., with some 30,000 AT&T customers complaining of technical difficulties, leaving them unable to place calls, text or access the internet. Within hours, the number of people suffering issues more than doubled, and by 9:30 a.m., some 74,000 people reported having network connection issues, according to downdetector.com, a website that provides real-time information about the status of online services.

AT&T, the nation’s largest service carrier, acknowledged the outages in a statement shortly thereafter, saying 75% of its network had been restored. According to downdetector.com, some 15,000 users still had issues as of 1 p.m.

So far, no reason has been given for the service problems, but the White House said multiple federal agencies have communicated with AT&T about the outages, Reuters reported. National Security spokesman John Kirby confirmed Thursday that both the FBI and the DHS are looking into the matter in addition to working with partners in the tech industry to “see what we can do from a federal perspective to lend a hand to their investigative efforts to figure out what happened here.”

Kirby added that while they “don’t have all the answers” yet, the investigative efforts are ongoing.

“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,” he said.

The U.S. Cybersecurity and Infrastructure Security Agency — an agency under the DHS umbrella, which is tasked with monitoring cyber threats — echoed Kirby’s statement in a confidential memo obtained by ABC News. It said “the cause of the outage is unknown, and there are no indications of malicious activity.”

The Federal Communications Commission is also investigating the outages.
