Nearly all (93,000 square feet) of the leases signed in the second quarter were for its most expensive product—turn-key datacenter space--which leased at average rate of $167 per square foot. In the same year-earlier period the average signed lease for turn-key datacenter space was at approximately $173 per square foot; it was $172 in the first quarter of 2009.

Leases commencing in the second quarter of 2009 totaled 115,000 square feet, including 93,000 square feet of turn-key datacenter space at an average lease rate of $166 per square foot. In the same year-earlier period, leases commenced for 138,500 square feet, including 86,200 square feet of turn-key datacenter space at an average rate of $185 per square foot; it was $179 in the first quarter of 2009.

Digital Realty Trust owns approximately 13 million square feet in 75 properties in 27 markets throughout Europe and North America. CEO Michael Foust says the leases commencing in the second quarter will contribute approximately $48.6 million of incremental revenue recognized in 2009.

"The supply of fully fitted-out datacenter space for corporate IT customers remains significantly constrained as a result of the limited availability of capital to build out this highly specialized space," he says. "We are encouraged by the level of new requirements we are tracking in our top markets and remain well-positioned to capture a disproportionate share of that demand."
