http://www.springnetunderground.net/ Not sure why you would want to go there though? It's all going to be homed off MCI (Kansas City). If I recall there may be some ring protection to STL. Might as well just go to some place like http://caverntechnologies.com/ where you will have less latency than going down to Springfield. In either instance you are in the $30 - $45/Mbps price range. Most people are in the major markets because not only is it less expensive to operate but they have more connectivity options, and better interconnects, etc.
