AT&T Restores Service After Massive, Nationwide Outage

An anonymous reader quotes a report from CNN Business: AT&T's network went down for many of its customers across the United States Thursday morning, leaving customers unable to place calls, text or access the internet. By a little after 3 pm ET, roughly 11 hours after reports of the outage first emerged, the company said that it had restored service to all impacted customers. 'We have restored wireless service to all our affected customers. We sincerely apologize to them,' AT&T said in a statement. The company added that it is 'taking steps to ensure our customers do not experience this again in the future.'

The Federal Communications Commission confirmed Thursday afternoon that it is investigating the outage. The White House says federal agencies are in touch with AT&T about network outages but that it doesn't have all the answers yet on what exactly led to the interruptions. Although Verizon and T-Mobile customers reported some network outages, too, they appeared far less widespread. T-Mobile and Verizon said their networks were unaffected by AT&T's service outage and customers reporting outages may have been unable to reach customers who use AT&T.

Thursday morning, more than 74,000 AT&T customers reported outages on digital-service tracking site DownDetector, with service disruptions beginning around 4 am ET. That's not a comprehensive number: It tracks only self-reported outages. Reports had been rising steadily throughout the morning but leveled off in the 9 am ET hour. By 12:30 pm ET, the DownDetector data showed some 25,000 AT&T customers still reporting outages. By 2 pm ET, fewer than 5,000 customers were still reporting issues. Earlier Thursday, AT&T acknowledged that it had a widespread outage but did not provide a reason for the system failure. By late morning, AT&T said most of its network was back online, and it confirmed Thursday afternoon that service was fully restored. According to an anonymous industry source, the issue for the outage appears to be related to how cellular services hand off calls from one network to the next, a process known as peering. They said there's no indication that it was the result of a cyberattack or other malicious activity.

The FCC confirmed that it is investigating the incident. 'We are aware of the reported wireless outages, and our Public Safety and Homeland Security Bureau is actively investigating,' the FCC said in a statement posted on X. 'We are in touch with AT&T and public safety authorities, including FirstNet, as well as other providers.'
