T-Mobile users were left with out talk, text and data for half the day yesterday.
The company says it’s fixed but the FCC wants answers. Service went down just after noon Eastern Time and it wasn’t restored until around one a.m. The nation’s number-three wireless carrier says the problem was not a Distributed Denial-of-Service attack, which is a common hack.
A blog post by CEO Mike Sievert blamed the outage on an “IP traffic-related issue” that created significant capacity issues in the network core. FCC Chairman Ajit Pai tweeted that the outage is unacceptable.
T-Mobile is set to absorb Sprint soon and that could be an awkward transition now. The provider’s network problems made it look like other carriers were down as well, but AT&T and Verizon say they have been working as normal.
