    Digital Realty Trust, Inc. (NYSE: DLR), the world's largest wholesale

Company to serve as its Senior Vice President of Technical Services. Manos
joins Digital Realty Trust from Microsoft where he was General Manager of

construction, design, operations and research for all Microsoft datacenters
around the world. In his new position at Digital Realty Trust, Manos will
oversee datacenter design and construction across the Company's global
portfolio of properties as well as oversee Technical Operations for the

influential people in the datacenter industry, Mike would no doubt be on
everyone's list and we are proud to have him join our team," said Michael F.
Foust, CEO of Digital Realty Trust. "We've had the opportunity to collaborate
with Mike on numerous occasions through our work with Microsoft, and he
shares our belief in the importance of advancing industrialization of the

an even bigger impact by enabling our customers to directly take advantage of
his broad expertise in datacenter architecture, construction and operations."

    "During my time at Microsoft, I have been able to devote a significant
portion of my time to industry education concerning datacenters, including
development of industry standards and shaping the way companies design and
build datacenters. That has been very rewarding. One of the most appealing
aspects about joining Digital Realty Trust is that I will be able to do that
on an even larger scale," said Manos. "Digital Realty Trust has been leading
a quiet revolution in the datacenter field that is impacting companies
everywhere. It has assembled an incredibly talented team of experts in
datacenter construction, energy efficiency and operations who have been on
the front line of modernizing the way people around the world design and run
datacenters. Joining Digital Realty Trust gives me a unique opportunity to
play a significant role in creating this new vision of the datacenter and
bringing those advancements to the industry as a whole. It's a very exciting
time to be in the datacenter field and an exciting time to be on the Digital
Realty Trust team."
