AT&T said the hourslong outage to its U.S. cellphone network Thursday appeared to be the result of a technical error, not a malicious attack.
The outage knocked out cellphone service for thousands of its users across the U.S. starting early Thursday before it was restored.
AT&T blamed the incident on an error in coding, without elaborating.
“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 Dallas-based company said.
