Research commissioned by Digital Realty Trust shows that in 2010, companies will increase their data centre floor space and expand into new locations as the European economy stabilises

DUBLIN, March 11, 2010 - Digital Realty Trust, Inc. (NYSE: DLR), the world's largest wholesale
data centre provider, announced the results of a new study which shows that
the majority of European companies are placing data centre expansion firmly
on the corporate agenda in 2010. The research addressed large enterprises
from France, Germany, Spain, the UK and Ireland, and reveals that data
centres have remained a priority for organisations despite the challenging

    Key findings of the new study include:

    - Four out of five companies (80 percent) surveyed are planning
      data centre expansions within the next year.
    - Almost two thirds (62 percent) of companies have built a new data
      centre in the past 24 months.
    - French companies have shown the broadest commitment to expansion,
      with nine out of ten (90 percent) planning to grow their data centres
      in 2010. In terms of immediate and definite expansion, German and
      UK/Irish companies showed the greatest commitment, with definite plans
      for 2010 growth reported by 30 percent and 29 percent of respondents,
    - The largest enterprises (those with annual revenues of euro 20B+)
      showed the greatest commitment to expansion plans. 43 percent of
      companies in this category will definitely grow their data centres in

"After a turbulent year for many European businesses, a remarkably high
proportion of them are planning data centre expansion projects in 2010. Even
with the challenge posed by limited capital expenditure budgets, companies
are treating data centre expansion as a necessity," said Bernard Geoghegan,
Senior Vice President at Digital Realty Trust who oversees International
Operations. "Our customers are reporting a pressing need to enlarge their
data centres, which are recognised as business-critical assets which support
plans for both recovery and future growth."

    Other findings of note in the new study include:

    - Four in five (79 percent) respondents who plan to expand in
      2010 say they will use a partner to implement their expansion plans.
    - Nearly half (49 percent) of European companies plan to expand
      their data centres in two or more locations, and 43 percent are looking
      to establish a data centre in a new location.
    - The most popular cities in which to site a new data centre are
      London (29 percent), Paris (21 percent) and Frankfurt (19 percent),
      consistent with the results of last year's survey.
    - On average, companies are seeking 1,400 square metres (15,100
      square feet) of raised floor for their expanded data centres.
      Respondents from UK/Ireland are seeking the largest data centres, with
      ambitions for 1,580 square metres (17,000 square feet), while space
      requirements are lower in France (1,230 square metres (13,200 square
      feet)) and Spain (1,240 square metres (13,400 square feet)).

"As we see in the 2010 survey data, London and Paris in particular
continue to see high demand for data centres. Each hosts European
headquarters for multinational corporations, both are well positioned to
address Western European markets, and consequently they are hubs for broader
economic investment. It is also clear that companies are seeking to expand in
multiple locations and establish facilities in new regions, suggesting that
the European data centre market will see new growth areas during the coming
years," Geoghegan added.

The study follows similar research released by Digital Realty Trust in
early 2009, and is based on a detailed survey of senior decision makers who
are either directly responsible for data centres or influence significant
decisions related to data centre operations within large European
organisations. The research was conducted by respected research firm Campos
Research and Analysis on behalf of Digital Realty Trust.
