I was spending the day at the Ferries 2009 conference in Seattle and towards the end of the day tried to send some text messages and make calls home to pick up my daughter, but nothing seemed to work. My T-Mobile data connection worked just fine, but both voice and text services were down. I then checked out Twitter and heard from others around the US that were experiencing the same thing. This service outage appeared to last for about three hours for me and everything is back up and running just fine.
Ina Fried also reported on the outage and you can see it affected many people. I have yet to see a statement from T-Mobile about what caused this outage and will post it if anything is revealed. This isn't the best news for T-Mobile following the huge Sidekick data outage. Personally, it was a minor inconvenience for me and given that I have always had outstanding service and connectivity through T-Mobile I am just happy to have all of my services back up and running.
There may have been businesses affected by the outage though so there is a possibility that some may not be as forgiving as me.
T-Mobile confirmed that this outage affected about 5% of their customers (I guess I was one of the lucky ones) and has fully been restored now.
