Bellevue-based T-Mobile USA today blamed a “software error” for a network outage that affected voice and messaging services for about 5 percent of its customers – including many in Seattle – on Tuesday.
“After investigating the cause, we have determined that a backend system software error had generated abnormal congestion on the network. T-Mobile has since implemented additional measures to help prevent this from happening in the future. We again apologize to those customers who were affected and may have been inconvenienced.”
No word yet on whether customers will get a one-day break on their Tmo bills.
