Springnet Underground

[Justin Shore <justin () justinshore com>]

Does anyone have any experience with the Springnet Underground in 
Springfield, MO?

In case people don't know it's a working limestone mine.  In the areas 
that have already been mined close to the entrance, they've sold or 
rented out space between the rock pillars that hold up the mine roof. 
The city of Springfield put in a data center and started selling 
services out of it that complimented their city-wide fiber plant.

They've been suggested as a site for hosting a cabinet full of gear. 
I'm wondering what the connectivity options are for that facility and so 
far haven't been able to get a straight answer from anyone.  For the 
most part it looks like the SprintNet folks want to sell you their own 
upstream which won't cut it for our needs.  AT&T serves the area of 
course but I will not have them as my last mile (or any mile for that 
matter).  Does L3 or any other large carrier have facilities there? 
Does anyone have any experience with the facility in general?

Thanks
 Justin
