AT&T said Friday that the 12-hour-long outage to its U.S. cellphone network Thursday didn’t appear to be caused by a cyberattack, blaming it on an “incorrect process.”
On Thursday, numerous customers reported that AT&T and Cricket, its subsidiary, were down for hours. Some 75,000 customers reported to DownDetector.com they were without cellphone service, texting, or internet access across the country, although that number is likely quite higher.
