Major Outage Hits AT&T, Verizon, And T-Mobile—Services Down Nationwide, Including 911 Calls

A major cellular outage has swept across the U.S., causing service disruptions across telecom providers, including AT&T Inc. T, Verizon Communications Inc. VZ and T-Mobile US Inc. TMUS.

What Happened: More than 51,000 outage incidents were recorded with AT&T’s service around 7 a.m. ET, as per data from Downdetector. The outage impacted several major cities, including San Francisco, Houston, and Chicago.

Customers of Verizon (VZ.N), T-Mobile (TMUS.O), and US Cellular also experienced service disruptions, according to Downdetector’s data.

While there were a little over 3,000 outage incidents for T-Mobile, Verizon outage incidents were lower at a little over 1,200.

However, a T-Mobile spokesperson told Benzinga that the network did not experience an outage and that it is operating normally.
