Digital Realty Trust, Inc. Receives BBB Rating From Fitch Ratings

SAN FRANCISCO, Nov. 4 /PRNewswire-FirstCall/ -- Digital Realty Trust, Inc. (NYSE: DLR), the leading owner and manager of corporate and Internet gateway datacenter facilities, today announced that Fitch Ratings initiated credit ratings on the Company with a 'BBB' Issuer Default Rating ('IDR').

According to Fitch's press release, Digital Realty has a credit profile consistent with a 'BBB' IDR due to three reasons: the size of its unencumbered property pool and unencumbered cash flow, leverage levels as measured by net debt to recurring operating EBITDA, and demonstrated access to various sources of capital providing financial flexibility.

A. William Stein, CFO and Chief Investment Officer, commented, "The 'BBB' rating from Fitch is another important milestone for Digital Realty Trust. Accessing the investment grade unsecured debt market is a critical component of our future funding strategy and will provide an attractive alternative to traditional mortgage finance, particularly in today's markets. This rating brings us another step closer to achieving that goal."

More information regarding Digital Realty Trust's rating can be found in the Fitch Ratings press release dated November 3, 2009 and on its website at www.fitchratings.com.
