Oops: AT&T Claims Snafu Caused By Software Update

A major cellphone outage affected users across the US early Thursday — even stopping some police departments from being able to receive 911 calls.

AT&T seemed to have experienced the largest number of issues, with nearly 32,000 reports at around 4:30 a.m., according to data from DownDetector, which tracks outages by collating status reports from sources including user-submitted errors on its platform.

More than 800 service outages were also reported on T-Mobile and Verizon, although a spokesperson for the latter put it down to users reporting problems trying to call people with other services.
