Colocation for a small business can be easily obtained from IT data center that is a reasonable distance from your location. It connects you by allowing you to place a server in the data center rack and sharing the bandwidth with other businesses. Generally one needs to set up his own machine and then take it to the data center of their choosing and place it inside their rack. Cost of bandwidth is the biggest advantage to colocation in a IT data center because for the same cost for business grade DSL you can get a single server with a dedicated line for about the same price plus you get more bandwidth. Any business savvy IT professional could figure this out.
