Comcast has dropped us a line to note they've launched 100 Mbps broadband service in the Twin Cities market. The tier, which offers 15 Mbps upstream, clocks in at a whopping $369.95 per month, and is intended for businesses. "This is a highly competitively priced when compared to typical business class T1 lines, many of which sell for hundreds of dollars per month and do not include the comprehensive software, applications and other features we offer," says Comcast.

The company says the tier will eventually be offered in additional markets and to residential customers, but is not specifying when. "We’re starting with commercial customers because we think this kind of speed will be of more interest to them," says Comcast spokesman Charlie Douglas. The business tier comes with Microsoft Communication Service, McAfee Security Suite software, Comcast's Web hosting starter package, a static IP, and business class twenty-four hour support.

We first reported rumors of a 100Mbps tier back in June. While Cablevision currently offers a 101 Mbps tier to residential customers, it costs $99 plus a $300 "activation fee." Comcast and Verizon have both publicly suggested they believe 100 Mbps for residential customers really isn't practical yet, and would exist solely as marketing bragging rights.
