CoreSite has acquired Comfluent, a Denver colocation and interconnection services provider for about US$3m, CoreSite announced Friday.

Besides its two data centers and strong customer base, CoreSite gains control of the Rocky Mountain Internet eXchange (RMIX). This the region’s largest internet exchange, and Comfluent manages it.

Tom Ray, CoreSite president and CEO, said the acquisition was another step in pursuing the wholesale data center provider’s strategy to enhance its position as a provider of data center services in key domestic markets that has a network focus.

“Comfluent has developed a blue-chip customer base and established itself as the clear leader in interconnection opportunity in Denver and the Rocky Mountain region,” Ray said.

Denver has a strategic interconnection location, placed along communication routes connecting the US West Coast to Chicago and Dallas, CoreSite said. This is the eighth market where CoreSite has extended its reach.

Comfluent serves more than 75 customers at two sites it leases that total about 9,300 sq ft of data center floor. RMIX provides access to more than 25 networks.

Comfluent’s founder Alf Gardner will remain with CoreSite, becoming general manager for the Denver region.
