San Francisco, Calif. (February 26, 2008) – Digital Realty Trust, Inc. (NYSE: DLR), a leading owner and manager of corporate and Internet gateway datacenter facilities, today announced financial results for its full year and fourth quarter ended December 31, 2007. The Company reported operating revenue of $395.2 million for the year and $105.9 million in the fourth quarter of 2007. For the year, net income was $40.6 million and net income available to common stockholders was $21.3 million, or $0.34 per diluted share, which includes an $18.0 million gain on sale of two assets during the first quarter of 2007. This compares to net income for 2006 of $31.4 million and net income available to common stockholders of $17.6 million, or $0.47 per diluted share, which includes an $18.0 million gain on sale of an asset in the third quarter of 2006. For the fourth quarter of 2007, net income was $5.6 million and net income available to common stockholders was $0.3 million, or $0.00 per diluted share. This compares to net income in the third quarter of 2007 of $5.1 million and net loss available to common stockholders of $0.2 million, or $0.00 per diluted share, and net income in the fourth quarter of 2006 of $6.4 million and net income available to common stockholders of $3.0 million, or $0.06 per diluted share.

Funds from operations (“FFO”) was $145.5 million for the year, or $2.05 on a diluted per share and unit basis, up 25.8% from $1.63 per diluted share and unit for the full year 2006. FFO was $38.9 million in the fourth quarter, or $0.53 on a diluted per share and unit basis, up 3.9% from $0.51 per diluted share and unit in the previous quarter; and up 10.4% from $0.48 per diluted share and unit in the fourth quarter of 2006. 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 income available to common stockholders to FFO and a definition of FFO are included as an attachment to this press release.

“Digital Realty Trust delivered another strong performance in 2007. We continued to expand our redevelopment program, providing high quality datacenter space to select U.S. and European markets where demand continues to outpace supply,” commented Michael F. Foust, Chief Executive Officer of Digital Realty Trust. “During the year we signed new leases totaling over 854,000 square feet for Turn-Key Datacenter™ and Powered Base Building™ space, of which nearly 357,000 square feet was signed during the fourth quarter. We also expanded our European footprint during the year to over 1 million square feet, which now represents approximately 10% of our total portfolio. Combined with our strategic capital raising activities during the year, we are well-positioned to execute on our disciplined growth strategy into 2008.”

Balance Sheet Update

Total assets grew to approximately $2.8 billion at December 31, 2007, from $2.2 billion at December 31, 2006. Total debt at December 31, 2007 was approximately $1.4 billion compared to $1.1 billion at December 31, 2006. Stockholders’ equity was approximately $1.0 billion, up from $709.8 million at December 31, 2006, primarily due to two follow-on public offerings, which generated $319.5 million in net proceeds that were used to reduce borrowings under the Company's revolving credit facility.

On October 22, 2007 the Company completed a follow-on public offering of 4,025,000 primary shares of common stock generating net proceeds of approximately $150.4 million. 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.

Subsequent to year end, on February 6, 2008 the Company completed a public offering of 13,800,000 shares of Series D Cumulative Convertible Preferred Stock, including the over-allotment option that was exercised, which generated approximately $333.6 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

Page 4

and redevelopment activities, and for general corporate purposes. The Series D Cumulative Convertible Preferred Stock will pay dividends quarterly at a rate of 5.500% per year on the $25.00 liquidation preference. The Series D Cumulative Convertible Preferred Stock will be convertible, at the holder's option, at an initial conversion rate of 0.5955 common shares per $25.00 liquidation preference (or an initial conversion price of $41.98 per common share), subject to adjustment upon the occurrence of certain events. The initial conversion price represents a 17.5% conversion premium over the closing sale price of the Company's common shares on January 31, 2008 on the New York Stock Exchange, which was $35.73 per share.

“Our strong performance in 2007 was facilitated by our ability to successfully access debt and equity markets in an environment where raising capital for real estate companies was severely constrained. Since the beginning of 2007, we have raised over $1.0 billion from our increased revolving credit facility, mortgage financings and refinancings, as well as equity offerings at very favorable terms,” said A. William Stein, Chief Financial Officer and Chief Investment Officer of Digital Realty Trust. “We expect that our focus on a strong balance sheet and financial flexibility will be a significant competitive advantage for Digital Realty Trust in 2008 and beyond.”

The Company is not changing its 2008 guidance at this time.

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

Page 9

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.
