SAN FRANCISCO and LONDON, January 7 /PRNewswire/ --

Digital Realty Trust, Inc. (NYSE: DLR), a leading owner and manager of corporate datacentres and Internet gateways, announced today the acquisition of Foxboro Business Park, a three building complex located in suburban London. The first building, Unit 1, totals over 20,000 square feet and is 100% leased to a leading international geophysical company as its corporate datacenter facility. Unit 2 is a 31,000 square foot warehouse that is 100% leased to a global manufacturer and marketer of home appliances. Unit 3 totals over 96,000 square feet of vacant space, in which the Company plans on building in phases approximately 58,000 square feet of Turn-Key Datacentre(TM) space.

"We are continuing to focus on adding both income producing assets as well as buildings suitable for redevelopment to meet the ongoing demand for Turn-Key Datacentres(TM) in the supply-constrained London market. This property meets both criteria, bringing an ideal combination of stability and longer term growth to our expanding European portfolio," commented Michael F. Foust, Chief Executive Officer of Digital Realty Trust.

"Concurrent with our phased redevelopment plans for Unit 3, we will be upgrading power to the site, which will ultimately offer our customers approximately 15MW of IT load," added Chris Crosby, Senior Vice President of Digital Realty Trust. "This project gives us an opportunity to offer as many as ten 5,800 square foot Turn-Key Datacentre(TM) PODs to corporate customers that have requirements for high quality datacentre space in the London market over the next few years. The space will be built out utilizing our POD Architecture(TM), which employs system plus system architecture providing a full 2N power train, as opposed to the shared electrical buss N+1 infrastructure typically utilized by other providers. Additionally, with our expertise in developing to green standards, including BREEAM in Europe and LEEDS in the US, we plan to deliver these PODS as sustainable datacentres."

Digital Realty Trust's Turn-Key Datacentres(TM) are scalable from hundreds of kilowatts of IT Load to megawatts of IT load and are located in markets throughout North America and Europe. Each Turn-Key facility is physically secure and features a state-of-the-art power and cooling architecture that has been optimized for green operation. Every Turn-Key Datacentre(TM) is built using the Company's proprietary POD Architecture(TM) and uses metered power to ensure that clients pay only for the power that they use. Each Turn-Key facility is also managed via Digital Realty Trust's Critical Facilities Management(TM) program to ensure the maximum uptime of mission critical applications.
