San Francisco, Calif. (November 6, 2007) – Digital Realty Trust, Inc. (NYSE: DLR), a leading owner and manager of corporate datacenters and Internet gateway facilities, today announced financial results for its third quarter ended September 30, 2007. The Company reported operating revenues of $104.8 million in the third quarter of 2007. Net income for the third quarter of 2007 was $5.1 million and net loss available to common

stockholders was $0.2 million, or $0.00 per diluted share. This compares to net income available to common stockholders of $2.6 million, or $0.04 per diluted share in the previous quarter, and $11.3 million, or $0.30 per diluted share for the third quarter of 2006, which reflects the non-recurring gain on sale of 7979 East Tufts Avenue in Denver, Colorado. Ignoring the $10.3 million gain on sale, net of minority interest, of 7979 East Tufts Avenue, net income available to common stockholders for the third quarter of 2006 would have been approximately $1.0 million, or $0.03 per diluted share. Funds from operations (“FFO”) was $35.9 million in the third quarter, or $0.51 per diluted share and unit, up 24% from $0.41 per diluted share and unit in the third quarter of 2006.

Acquisition and Leasing Activity

During the third quarter of 2007 the Company completed four property acquisitions. On August 10, the company acquired 900 Walnut Street and 210 Tucker Boulevard, located in St. Louis, Missouri, for a combined purchase price of $55.3 million, including a $2.3 million earn out payment made at closing. The seven-story 900 Walnut building serves as the premier Internet gateway facility for the St. Louis region, totals approximately 112,300 rentable square feet and is 99% leased. The 18-story 210 Tucker Boulevard building serves as a multi-tenant datacenter facility and contains approximately 201,600 rentable square feet, including 62,000 square feet of redevelopment space. Excluding the redevelopment space, the building is approximately 95% leased.

On August 22, the Company acquired One Savvis Parkway, a 156,000 square foot office building located in suburban St. Louis, Missouri. The purchase price was $27.7 million. The five-story building is 100% leased on a triple net basis through June 2017 to Savvis, Inc. The building serves as Savvis’s corporate headquarters and national Network Operations Center facility.

On September 5, the Company acquired a 50% ownership interest in a joint venture partnership that owns 1500 Space Park Drive, a premier datacenter development project located in Santa Clara, California, for approximately $3.7 million. Along with our joint venture partner, we guaranteed a secured floating rate loan in the amount of $5.5 million that encumbers the property. The property consists of an existing 49,900 square foot building, including over 34,000 square feet of Turn-Key Datacenter™ space under construction, and additional land to support the development of new datacenter facilities with the potential of up to 290,000 square feet.

As of November 6, 2007, the Company’s portfolio comprises 67 properties, excluding one property held as an investment in an unconsolidated joint venture, consisting of 88 buildings totaling approximately 12.0 million rentable square feet, including 1.7 million square feet of space held for redevelopment. The portfolio is strategically located in 26 key technology markets throughout North America and Europe. Excluding space held for redevelopment, occupancy across Digital Realty Trust’s property portfolio was 95.1% at September 30, 2007.

For the quarter ended September 30, 2007, leases commenced on approximately 166,200 square feet of datacenter space at an average annualized rent of approximately $64.00 per square foot. The Company also commenced leases on 25,500 square feet of non-technical space at an average annualized rent of approximately $18.00 per square foot. The 209,600 square feet of leases signed during the third quarter includes over 197,000 square feet of datacenter space at an average annualized rent of approximately $61.00 per square foot and 12,600 square feet of non-technical space at an average annualized rent of approximately $17.00 per square foot.

Over 297,800 square feet of redevelopment space was under construction during the quarter, consisting of 133,900 square feet of Turn-Key Datacenter™, 39,400 square feet of build-to-suit datacenter and 124,500 square feet of new Powered Base Building™. Approximately 187,400 square feet space held for redevelopment was converted to the operating portfolio during the third quarter of 2007, which includes 35,200 square feet of Turn-Key Datacenter™ as well as 152,200 square feet of space that was leased on a Powered Base Building™ basis.

“Our strong performance in the third quarter reflects our market-dominant position resulting from the successful execution of our business strategy. Our proven business model has made us the preferred real estate solutions provider for global Fortune 1000 corporate datacenter, Internet enterprise, IT and communications services customers, which continue to drive demand for our Turn-Key Datacenter™ and Powered Base Building™ space,” said Michael Foust, Chief Executive Officer of Digital Realty Trust.

Balance Sheet Update

Total assets grew to approximately $2.6 billion at September 30, 2007, from $2.2 billion at December 31, 2006. Total debt at September 30, 2007 was approximately $1.3 billion compared to $1.1 billion at December 31, 2006. Stockholders’ equity was $921.4 million, up from $709.8 million at December 31, 2006, primarily due to the issuance of 7.0 million shares of Series C Cumulative Convertible Preferred Stock completed during the second quarter 2007.

On August 31, 2007 the Company modified, extended and expanded its senior unsecured revolving credit facility, increasing the total capacity to $650 million from $500 million from the previous facility. The purpose of the enhanced credit facility is to provide funds for acquisitions, development, redevelopment, repayment of debt, working capital and general corporate purposes. The $650 million facility is expandable to $750 million and has sixteen participant banks, up from thirteen banks in the previous facility. The credit facility now

Page 3

matures in August 2010 and has two one-year extension options. The applicable margin ranges from 12.5 to 25 basis points lower than the applicable margin for the earlier facility and the covenants have been modified to provide Digital Realty Trust with enhanced financial flexibility and increased borrowing capacity.

On August 9, 2007, the Company’s unconsolidated joint venture completed the re-financing of 2001 6^th Avenue, located in Seattle, Washington. The new loan for $110.0 million has a 10-year maturity with no principal amortization for three years, and a fixed interest rate of 6.37%.

On September 5, 2007, in conjunction with the acquisition of the 50% ownership interest in the consolidated joint venture that owns 1500 Space Park Drive in Santa Clara, California, the Company, along with its joint venture partner, guaranteed a secured floating-rate loan in the amount of $5.5 million that encumbers the property. The loan bears an interest rate of LIBOR + 2.75% and matures on April 5, 2008.

Subsequent to the end of the quarter, on October 22, 2007 the Company completed a follow-on public offering of over 4.0 million primary shares of common stock generating net proceeds of approximately $150.5 million. The Company utilized the net proceeds from the offering to temporarily repay borrowings under its credit facility. The Company intends to reborrow amounts under its credit facility from time to time to acquire additional properties, to fund development and redevelopment opportunities and for general corporate purposes.

“Our ability to modify our credit facility, providing us with greater financial flexibility in the U.S. and abroad at more favorable borrowing costs and a longer maturity – particularly under the current market conditions – demonstrates the success of our business model,” said A. William Stein, Chief Financial Officer and Chief Investment Officer of Digital Realty Trust. “Combined with the subsequent common stock offering, we are well-positioned to fund our ongoing acquisitions, leasing, development and redevelopment programs and continue to grow the Company.”

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.
