Digital Realty Trust, Inc. Acquires Major Datac...

SAN FRANCISCO and LONDON, December 18 /PRNewswire/ --

    - Acquisitions include one fully leased property and one value-add 
redevelopment opportunity, bringing the European portfolio to over 1 million
square feet

    Digital Realty Trust, Inc. (NYSE: DLR), a leading owner and manager of
corporate datacentres and Internet gateways, announced today the acquisition
of two properties in Europe. The first property, Cressex 1, is located in
suburban London and totals approximately 51,000 rentable square feet of
redevelopment space. The purchase price was 6.5 million British pounds
sterling. The Company plans to build 20,000 square feet of raised floor,
Turn-Key Datacentre(TM) space offering 2.88 MW of IT load, as well as 15,000
square feet of supporting office/business continuity space. Construction is
scheduled to commence in the first quarter of 2008 with completion expected
by September 2008.

    The second property, Naritaweg 52, is located in Amsterdam, Netherlands.
It was purpose built as a datacentre in 2001 and totals over 63,000 rentable
square feet. The purchase price was 18.9 million euros. The building is

    100% leased through September 2011 to a leading international information
technology services company and consists of over 24,000 square feet of raised
floor technical space and nearly 21,000 square feet of office and other

    "The addition of these two properties to our portfolio represents our
continued expansion into select European markets, and is consistent with our
strategy of acquiring high quality income producing assets along with
value-add properties suitable for redevelopment," commented Michael F.
Foust, Chief Executive Officer of Digital Realty Trust.

    "We are continuing to see strong demand from customers seeking Turn-Key
Datacentre(TM) space in the London market, where supply remains very
limited," added Chris Crosby, Senior Vice President of Digital Realty Trust.
"Redeveloping Cressex 1 gives us an opportunity to bring two 10,000 square
foot PODs of Turn-Key Datacentre(TM) space to the supply-constrained London
market much more quickly than if we were to develop a facility from the
ground up -- meeting the current demand while avoiding much of the risk
associated with greenfield developments. Building out the space utilizing our
POD Architecture(TM) will bring several unique elements to the UK market. The
POD Architecture(TM) 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 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.
