Equinix Has Filled 57 Percent of DC Space

Our utilization rate represents the percentage of our cabinet space billing versus total cabinet space available. Our utilization rate grew to 57% as of March 31, 2006 from 45% as of March 31, 2005. Although we have substantial capacity for growth, our utilization rates vary from market to market among our IBX centers in the 11 markets across the U.S. and Asia-Pacific. ... Power and cooling requirements for some customers are growing on a per unit basis. As a result, customers are consuming an increasing amount of power per cabinet. We could face power limitations in our centers even though we may have additional physical capacity available within a specific IBX center.
