If you live in the Southeastern part of the U.S. and were unable to get cell phone service last night, you weren’t alone.
The outages started around 2:30 p.m. ET on Tuesday and lasted approximately five hours or more, depending on your carrier, affecting customers across Tennessee, Kentucky, and other parts of the Southeast, according to Knoxville’s WATE 6. The problem wasn’t limited to a single carrier—service went down across a number of providers including AT&T, Verizon, T-Mobile, Sprint, as well as regional providers U.S. Cellular and Cricket.
During the outage, affected users were unable to get Internet or cell service on their devices. The website Down Detector reported more than 10,000 AT&T, 1,000 Verizon, 7,000 T-Mobile, 300 Sprint, 250 U.S. Cellular, and 75 Cricket Wireless users were affected.
At this point, cell phone service has been restored; Verizon had everything back up and running just after 8 p.m. while AT&T fixed the problem by 10 p.m. The exact cause of the outage is not known, though AT&T blamed it on a “hardware-related network issue.”
U.S. Cellular, meanwhile, pointed to an unnamed third-party vendor that transmits traffic from cell sites to wireless devices. The company said two of this vendor’s routers were down, which caused the service interruption.
While the problem was mainly concentrated in the Southeast, it also affected cell phone users in San Francisco, Los Angeles, Dallas, and New York City, though to a lesser extent, according to Engadget.
