[outages] T-Mobile Voice Outage

Does anyone have any information on the current T-Mobile outage. I am in Chicago, I have no voice service "Call Failed" when I attempt to make a call, incoming callers are being told my line has been disconnected Same location as me, 3 other TMO BlackBerries have fine service. Data seems to be unaffected. I know of 3 other users having this issue as well throughout the Chicagoland area. Thanks Matt
