More than 10 million subscribers cannot use mobile communication.
Residents of the United States have experienced massive disruptions in mobile communication, with AT&T subscribers experiencing the greatest problems. The outages began around 4 a.m. ET (1 a.m. PST) and continue to come in, surpassing 73,000 reports of issues at AT&T at the time of writing. Verizon and T-Mobile USA services have also experienced widespread disruptions, albeit on a smaller scale than AT&T.
AT&T appears to have taken the brunt of the blow, while T-Mo and Verizon subscribers are experiencing secondary effects. Representatives of T-Mobile and Verizon said that their networks are operating normally, and the problems are probably related to attempts to contact subscribers of other operators. AT&T confirmed the problem and said it is working to restore service, recommending that you use Wi-Fi calls until the problem is resolved.
The cause of the crash, which is ongoing at the time of publication, was not named. The outage is so severe that some AT&T subscribers are unable to make or receive calls, including calls to 911, as the San Francisco Fire Department warned last week.
Major cities, including Atlanta, Dallas, and Houston, are marked on the crash report map. In recent years, the U.S. has seen a shift in ownership of cell towers: most of them are now owned by real estate investment funds like American Tower and Crown Castle, which have purchased tens of thousands of towers from AT&T, Verizon, and T-Mobile.
AT&T reported that the network began to recover: teams quickly took action, and already three-quarters of the network is restored. Work continues to restore the service for the remaining customers.
Cloudflare has recorded a significant drop in IPv4 and IPv6 connections for AT&T, leading some network administrators to speculate that the problem is related to BGP.
