If you’re an AT&T customer, you’ve likely been affected by the widespread cell outage that left users across the US unable to place calls, text, or access the Internet.
Though the company provided no official reason for the outage, the issue appears to be related to how cellular services hand off calls from one network to the next, a process known as peering, according to CNN.
While Verizon and T-Mobile customers also reported some network outages, they appeared to be less widespread.
