T-Mobile Web Services Outage?

Seems like T-Mobile has been having issues with their websites and web services like their mobile browsing and access to customer minutes used and the like. It may have been a pretty big outage as both computer and handheld/mobile access to their sites and services seem to have been down for at least 1.5 hours. The My T-Mobile site did come up a few minutes ago, but there was no data available on billing or minutes used.
