- New Properties Increase Company's Footprint in Two Top Markets

    Digital Realty Trust, Inc. (NYSE: DLR), a leading owner and manager of
corporate and Internet gateway datacenters, announced today the acquisition
of two properties located in two of the Company's top markets: Northern New
Jersey and the United Kingdom.

    The first property is located at 650 Randolph Road in Franklin Township,
New Jersey. The recently completed purpose-built datacenter shell contains
127,800 square feet, which is capable of supporting approximately 70,000
square feet of raised floor. The Company plans to contribute the property to
its redevelopment inventory and make additional improvements to the building
to meet its Powered Base Building(TM) specification. The Company plans to
market the facility to financial service companies, system integrators and
other Fortune 1000 firms.

    The second property, Reynolds House Datacenter, is located in Manchester,
U.K. The 38,600 square foot income producing facility was purpose built as a
datacenter in 2001 and contains nearly 23,000 square feet of raised floor,
with the potential for an additional 7,000 square feet of raised floor. The
facility is fully leased to three tenants on long term bases.

    "The addition of 650 Randolph Road in Franklin Township, New Jersey
provides us with additional redevelopment inventory in a market that
continues to experience strong demand for our Turn-Key Datacenter and Powered
Base Building(TM) solutions. It is ideally located for companies seeking
large blocks of high quality datacenter space in the Metro New York market,"
commented Michael F. Foust, Chief Executive Officer. "The addition of
