Digital Realty Trust, Inc. Acquires Datacentre ...

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.
