New data from TeleGeography’s Colocation Database reveal that colocation service providers are struggling to keep up with demand. Despite significant new construction, colocation site capacity is more constrained in 2010 than it was in 2009. More than 41% of sites surveyed by TeleGeography were at least 80% full at mid-2010, up from 34% of sites a year earlier.

A combination of established and emerging colocation operators has invested heavily in new development in the last two years. Equinix alone has added more than one million gross square feet of new colocation site space and more than 42 megawatts of colocation power capacity since September 2008. These numbers represent newly built capacity and do not reflect the company’s acquisition of Switch and Data. TelecityGroup, the CSF Group and Internap have also recently completed significant development, each with well over 100,000 sq ft of new space. TelecityGroup has added 22 megawatts of new power capacity to its sites over the past two years.
