San Francisco, Calif. (August 6, 2008) – Digital Realty Trust, Inc. (NYSE: DLR), the leading owner and manager of corporate and Internet gateway datacenter facilities, today announced financial results for its second quarter ended June 30, 2008. The Company reported operating revenue of $123.8 million in the second quarter of 2008, up 8.1% from $114.5 million in the first quarter of 2008 and up 29.5% from $95.6 million in the second quarter of 2007. For the second quarter of 2008, net income was $13.8 million and net income available to common stockholders was $3.7 million, or $0.05 per diluted share. This compares to net income in the first quarter of 2008 of $11.1 million and net income available to common stockholders of $2.9 million, or $0.04 per diluted share, and net income in the second quarter of 2007 of $7.8 million and net income available to common stockholders of $2.6 million, or $0.04 per diluted share.

“As more and more customers look to expand their datacenter operations, our Turn-Key Datacenter™ has become the preferred time-to-market infrastructure solution for many corporate, Internet enterprise and system integrator customers who need to accommodate their growing IT requirements and get new applications up and running quickly,” commented Michael F. Foust, Chief Executive Officer of Digital Realty Trust. “Our strong performance is driven by our ability to deliver new product in key markets throughout the U.S. and Europe in time to meet our customers’ requirements.”

Funds from operations (“FFO”) was $44.4 million in the second quarter of 2008, or $0.59 on a diluted per share and unit basis, up 1.7% from $0.58 per diluted share and unit in the previous quarter; and up 15.7% from $0.51 per diluted share and unit in the second quarter of 2007.

“If one adjusts for approximately $0.02 per diluted share of non-recurring items in first quarter 2008 FFO, the quarter over quarter increase to $0.59 per diluted share and unit in the second quarter of 2008 would have been 5.4%,” added A. William Stein, Chief Financial Officer and Chief Investment Officer of Digital Realty Trust.

FFO is a supplemental non-GAAP financial measure used by the real estate industry to measure the operating performance of real estate companies. FFO should not be considered as a substitute for net income determined in accordance with U.S. GAAP as a measure of financial performance. A reconciliation from U.S. GAAP net

Acquisitions and Leasing Activity

On June 13, 2008, the Company acquired 650 Randolph Road in Franklin Township, New Jersey. The recently completed purpose-built datacenter shell totals 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™ specifications. The Company plans to market the facility to financial service companies, system integrators and other Fortune 1000 companies looking for large blocks of high quality datacenter space in the Metro New York market.

On June 20, 2008, the Company acquired Reynolds House Datacenter, located in Manchester, U.K. The 38,000 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.

On June 30, 2008, the Company acquired a 50% interest in 1201 Comstock Street, a site contiguous to its 1100 Space Park Drive and 1500 Space Park Drive properties in Santa Clara, California. The 24,000 square foot datacenter is currently under construction and will contain approximately 14,000 square feet of raised floor. Concurrent with the acquisition, a leading technology company signed a lease for the entire building. The tenant is expected to take occupancy upon completion of construction in January 2009.

As of August 6, 2008, the Company’s portfolio comprises 74 properties, excluding one property held in an unconsolidated joint venture, consisting of 96 buildings totaling approximately 12.9 million rentable square feet, including 1.9 million square feet of space held for redevelopment. The portfolio is strategically located in 27 key technology markets throughout North America and Europe.

The Company commenced leases during the quarter totaling approximately 138,500 square feet of space. This includes 86,200 square feet of Turn-Key Datacenter™ space leased at an average annual GAAP rental rate of approximately $185 per square foot and 52,000 square feet of non-technical space leased at an average annual GAAP rental rate of approximately $26 per square foot.

In addition, the Company signed leases during the quarter totaling 121,800 square feet of space. This includes 106,700 square feet of Turn-Key Datacenter™ space leased at an average annual GAAP rental rate of approximately $173 per square foot and 14,500 square feet of non-technical space leased at an average annual GAAP rental rate of approximately $25 per square foot.

Balance Sheet Update

Total assets grew to approximately $3.1 billion at June 30, 2008, from $2.8 billion at December 31, 2007. Total debt at June 30, 2008 was unchanged at approximately $1.4 billion from December 31, 2007. Stockholders’ equity was approximately $1.4 billion, up from $1.0 billion at December 31, 2007, primarily due to the public offering of Series D Cumulative Convertible Preferred Stock in the first quarter of 2008.

Subsequent Events

On July 17, 2008, the Company closed an $80 million secured financing on 3 Corporate Place located in Piscataway, New Jersey. The loan has a three-year maturity with two one-year extensions at an interest-only rate of 6.72% per annum.

On July 21, 2008, the Company completed a public offering of 5,750,000 shares of Common Stock, including the over-allotment option that was exercised, which generated approximately $211.6 million in net proceeds. The Company utilized the net proceeds from the offering to temporarily repay borrowings under its revolving credit facility, to fund acquisitions, development and redevelopment activities, and for general corporate purposes.

On July 24, 2008, the Company closed on a $200 million uncommitted, unsecured Prudential Shelf Facility. The three-year, multi-currency facility provides for draws, from time to time, as approved by Prudential with an average life and final maturity of up to seven years and ten years, respectively. Concurrent with the close of the Facility, the Company made an initial draw of $25 million with an interest-only rate of 7.00% per annum and a three-year maturity. The Company intends to use the proceeds of the initial notes and any additional notes to acquire properties, to fund development and redevelopment activities and for general corporate purposes.

In addition, on July 25, 2008, the Company increased the total commitments under its revolving credit facility from $650 million to $675 million with a new $25 million commitment from Deutsche Bank.

“We have continued to obtain capital from a variety of sources to maintain our liquidity and strong balance sheet in the face of extremely volatile capital markets and challenging economic conditions,” said A. William Stein, Chief Financial Officer and Chief Investment Officer of Digital Realty Trust. “As a result of our performance, including a shift in our leasing mix in favor of our Turn-Key Datacenter product, and with better visibility towards our full year 2008 results, we are increasing our FFO guidance by $0.05 per diluted share for the year to $2.40 - $2.50.”

2008 Revised Outlook

FFO per diluted share and unit for the year ending December 31, 2008 is projected to be between $2.40 and $2.50, an increase of $0.05 from the previous 2008 FFO guidance of between $2.35 and $2.45 per diluted share and unit. This revised guidance represents projected FFO growth of 17.1% to 22.0% over FFO per diluted share and unit of $2.05 for the year ended December 31, 2007. A reconciliation of the range of 2008 projected net income to projected FFO follows:

		(Low - High)
Net income available to common stockholders per diluted share		$0.45 - 0.55
Add:
Real estate depreciation and amortization as adjusted for minority interest		$1.95
Projected FFO per diluted share		$2.40 - 2.50

The revised 2008 guidance provided by Digital Realty Trust in this press release is based on the following assumptions as of August 6, 2008:

• Total acquisitions for the full year in the range of $115 million to $180 million, consisting of $65 million to $75 million of vacant properties for its redevelopment program and $50 million to $105 million of income producing properties at average cash cap rate of 8.00%;

• The commencement of leases for approximately 840,000 square feet to 950,000 square feet of Turn-Key Datacenter™ and Powered Base Building™ space at an average annualized gross rent of $115 per square foot;

• The commencement of leases for 100,000 square feet to 125,000 square feet of basic commercial space at an average annualized gross rent of $23 per square foot;

• Total capital expenditures for its redevelopment program of $600 million; and

• Total G&A of $41 million.

Note Regarding Funds From Operations

Digital Realty Trust calculates Funds from Operations, or FFO, in accordance with the standards established by the National Association of Real Estate Investment Trusts, or NAREIT. FFO represents net income (loss) available to common stockholders and unitholders (computed in accordance with U.S. GAAP), excluding gains (or losses) from sales of property, real estate related depreciation and amortization (excluding amortization of deferred financing costs) and after adjustments for unconsolidated partnerships and joint ventures. Management uses FFO as a supplemental performance measure because, in excluding real estate related depreciation and amortization and gains and losses from property dispositions, it provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. Digital Realty Trust also believes that, as a widely recognized measure of the performance of REITs, FFO will be used by investors as a basis to compare our operating performance with that of other REITs. However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our properties that result from use or market conditions, nor the level of capital expenditures and leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effect and could materially impact our results from operations, the utility of FFO as a measure of our performance is limited. Other REITs may not calculate FFO in accordance with the NAREIT definition and, accordingly, our FFO may not be comparable to such other REITs’ FFO. Accordingly, FFO should be considered only as a supplement to net income as a measure of our performance.
