SoftLayer Moves Headquarters and Data Center to Digital Realty Trust Property

SAN FRANCISCO, Feb. 18 /PRNewswire-FirstCall/ -- Digital Realty Trust, Inc. (NYSE: DLR), the world's largest wholesale datacenter provider, has completed a multi-faceted lease agreement with SoftLayer® that combines its headquarters and data centers in a Digital Realty Trust property in the Dallas area. SoftLayer Technologies, a leading provider of on-demand IT services, has signed a lease for office and data center space in a Digital Realty Trust building with the option to occupy the entire building to meet the company's future expansion requirements. SoftLayer also has naming rights for the standalone building, which will serve as the company's global headquarters and operations center.

"We were running out of office space and data center capacity in our current facilities, so we needed to find a solution that could accommodate our growth. The Digital Realty Trust property gives us tremendous flexibility to expand over time and enables us to house our offices and IT operation under the same roof. That has tremendous efficiencies for our operations and benefits for our customers," said Lance Crosby, CEO of SoftLayer. "The Digital Realty Trust building allows us to expand our IT operations incrementally and cost effectively as our business grows."

"We are pleased that SoftLayer selected a Digital Realty Trust property as the new home for its corporate headquarters and IT operations," said Brent Behrman, Vice President, Global Sales of Digital Realty Trust. "SoftLayer was looking for a standalone property that would provide first-rate office space as well as technical space for its IT service operations. We will convert part of the facility whose lease was expiring into a state of the art datacenter with ample power and fiber connectivity to support SoftLayer's datacenter operations. This lease demonstrates our ability to add value to our existing properties through our redevelopment program."

Mr. Crosby of SoftLayer added: "This is a first step in an aggressive growth plan for SoftLayer in 2010. Adding capacity in Dallas is a first priority, but we will continue to expand both our data center and network capabilities in the coming months to satisfy the needs of our growing customer base."
