Dublin and Paris, June 25, 2009; Digital Realty Trust, Inc. (NYSE: DLR), the world's largest wholesale datacentre provider, has completed a Turn-Key DatacentreSM lease agreement with Capgemini (www.capgemini.com), one of the world's foremost providers of consulting, technology and outsourcing services. Under this agreement, Capgemini will establish a new datacentre in a Digital Realty Trust property in France during the summer to support the growth of its datacentre infrastructure.

"We are delighted to be working with Capgemini on this important datacentre project for its global IT strategy.
