NEW YORK (AP) — The head of the United States (US) communications regulator said T-Mobile’s nationwide, hours-long outage on Monday was “unacceptable” and that the Federal Communications Commission (FCC) will investigate.
T-Mobile, one of the country’s three largest cellphone service providers, said it had a “voice and text wireless issue” that began around noon EDT on Monday. The company said at 1am on Tuesday that all problems had been resolved.
The company blamed an Internet-traffic issue that caused problems with its network for the outage.
AT&T and Verizon both said their networks were operating normally. But calls between their customers and T-Mobile customers could have run into trouble because of T-Mobile’s issues, creating the impression of a widespread communications failure.
The FCC has fined telecom companies in the past for network outages. T-Mobile paid a USD17.5 million fine for two nationwide service outages on the same day in August 2014, which together lasted three hours and prevented customers from being able to call 911.
