In a statement on its website, AT&T confirmed the resolution of the outage and apologized to its customers. The carrier also assured that it is “taking measures” to prevent a similar incident from happening again, although it did not reveal the cause of the significant disruption.
The Federal Communications Commission (FCC) also acknowledged the outage and is “actively investigating.”
During the outage, AT&T advised customers to use Wi-Fi and Wi-Fi calling, assuming they had access to Wi-Fi. Other carriers, including Verizon and T-Mobile, were not affected and operated as usual.
Rumors were circulating about a possible cyberattack, but AT&T denied it in its initial review. Previously, deputy executive director of the US Cybersecurity and Infrastructure Security Agency Eric Goldstein told CNN that the agency is “working closely with AT&T to understand the cause of the outage.”
Because matter: This outage was not an isolated incident affecting only AT&T.
A major cellular service outage had spread across the United States, causing service outages among telecom providers, including AT&T, Verizon Communications Inc. VZand T-Mobile US Inc. TMU.
More than 51,000 AT&T service outage incidents were recorded around 7 a.m. ET on Thursday, impacting several major cities, including San Francisco, Houston and Chicago.
