Switch & Data Facilities Company, Inc.

Announces Fourth Quarter and Full Year 2006 Financial Results

• Reports Strong Fourth Quarter and Full Year 2006 Revenue

• Key Customer wins and expansions including, Time Warner Telecom, Limelight, and Verisign

• Strong year for Customer acquisitions

Tampa, Florida – March 28, 2007 - Switch and Data Facilities Company, Inc. (NASDAQ:SDXC), a leading provider of network neutral interconnection and colocation services, today reported financial results for the three months and year ended December 31, 2006.

Fourth Quarter and Full Year 2006 Review

For the three months ended December 31, 2006 total revenue increased 9.5% to $29.3 million from $26.7 million in the comparable period in 2005. Total revenue was $111.8 million for the year ended December 31, 2006, a 6.1% increase over revenue of $105.4 million for the prior year ended December 31, 2005. Recurring revenue, which consists of colocation and interconnection services, was $27.9 million in fourth quarter 2006, an increase of 9.2% over the comparable period in 2005. For the full year 2006, recurring revenue increased 6.1% to $106.9 million as compared to $100.8 million the prior year. The increase in recurring revenue was primarily due to the sale of services to new and existing customers.

For fourth quarter 2006, non-recurring revenue, representing one time installation fees and services, was $1.4 million, compared to $1.2 million in the prior year. For the full year, non-recurring revenue increased to $5.0 million from $4.6 million for the year ended December 31, 2005 due to increased support services.

Cost of revenues, excluding depreciation and amortization, for the three months ended December 31, 2006 was $15.2 million as compared to $14.8 million for the three months ended December 31, 2005. For the year ended December 31, 2006 cost of revenues increased by $5.6 million, or 10.2%, to $60.4 million as compared to $54.8 million for the year ended December 31, 2005. The increase in cost of revenues was primarily due to the expansion of the Company’s facilities in several markets, including the San Francisco Bay area and New York City.

For the three months ended December 31, 2006, sales and marketing costs increased approximately 22.0% to $3.1 million from $2.5 million for the comparable quarter in 2005. Sales and marketing expenses increased 25.2% to $12.3 million for the year ended December 31, 2006 compared to $9.8 million for the year ended December 31, 2005. The increase in sales and marketing costs was due primarily to an increase in commissions and increased headcount.

General and administrative expenses declined by $0.9 million for the three months ended December 31, 2006 to $2.5 million due primarily to lower professional fees. For the year ended December 31, 2006 general and administrative expenses were $10.4 million, an increase of 8.4% over the prior year primarily due to increased headcount.

Adjusted EBITDA, which is a non-GAAP measure, and which the Company defines as operating income from operations, plus depreciation and amortization, stock-based compensation expense and other non-cash items such as deferred rent and asset impairment was $9.0 million in the fourth quarter of 2006 and $31.8 million for the 12 months ended December 31, 2006 compared to $7.4 million and $34.6 million in the comparable periods, respectively in 2005.

Capital expenditures were $4.4 million and $21.3 million in the fourth quarter and full year 2006, respectively.

Keith Olsen, CEO and President commented, “Our sales momentum continues to build on the progress we achieved in 2006. We increased billable cabinet equivalents by 15%, ended the year with over 17,500 cross connects and reduced churn to less than 1% in the fourth quarter. We believe our investments in Palo Alto, New York, Denver and Chicago have provided us the platform for growth for both our existing customers, as well as new customers.” Mr. Olsen further added, “Customers are monetizing our marketplaces, Verisign is an example of how a customer extended their services by leveraging our footprint, while delivering to the industry a leading VoIP ENUM solution. We are entering 2007 with a strong financial position, significant operational improvements and most important, the momentum to drive even better results in 2007.”

George Pollock, Jr., the Company’s CFO, also added “The net proceeds to the Company from the IPO were approximately $142 million. The financial position of the Company was materially improved as we used the majority of the proceeds to repay borrowings, reducing our long-term debt by approximately $104 million.”

Business Outlook

For the full year 2007, the Company expects total revenue to be approximately $127 million with $122 million from recurring revenue. Adjusted EBITDA is expected to be approximately $40 million. Adjusted EBITDA margins are projected to be approximately 32%.

Capital expenditures for 2007 are estimated to be in the range of $28 million to $30 million.

A reconciliation between GAAP information and non-GAAP information contained in this press release can be found in the table immediately following the Consolidated Statements of Changes in Financial Position as well as on the Company’s website in the Investor Relations section.

Switch and Data does not provide forward-looking guidance for certain financial data, such as depreciation, amortization, net income (loss) from operations, cash generated from operating activities and cash used in investing activities, and as a result, is not able to provide a reconciliation of GAAP to non-GAAP financial measures for forward-looking data. The Company intends to calculate the various non-GAAP financial measures in future periods consistent with how it was calculated for the three and twelve months ended December 31, 2005 and 2006, presented within this press release.

* Monthly recurring revenue represents new service agreements entered into by new and existing customers during the given quarter. Revenue from these agreements will recur monthly over the life of the agreement.

Adjusted EBITDA RECONCILIATION

The following is a reconciliation of the Company’s net income (loss) for the 3 and 12 months month periods ended December 31, 2005 and December 31, 2006 to Adjusted EBITDA.

Switch and Data uses Adjusted EBITDA:

• As measurements of operating performance because they assist management in comparing the operating performance on a consistent basis as they remove the impact of items not directly resulting from the operations;

• For planning purposes, including the preparation of its internal annual operating budget;

• To establish targets for certain management compensation; and

• To evaluate the Company’s capacity to incur and service debt, fund capital expenditures and expand the business.

Adjusted EBITDA as calculated by the Company is not necessarily comparable to similarly titled measures used by other companies. In addition, Adjusted EBITDA: (a) does not represent net income or cash flows from operating activities as defined by GAAP; (b) is not necessarily indicative of cash available to fund the Company’s cash flow needs; and (c) should not be considered as alternatives to net income, operating income, cash flows from operating activities or the Company’s other financial information as determined under GAAP.

The Company prepares Adjusted EBITDA by adjusting EBITDA to eliminate the impact of a number of items that it does not consider indicative of its core operating performance. Investors are encouraged to evaluate each adjustment and the reasons the Company considers them appropriate. As an analytical tool, Adjusted EBITDA is subject to all of the limitations applicable to EBITDA. In addition, in evaluating Adjusted EBITDA, investors should be aware that in the future the Company may incur expenses similar to the adjustments in this presentation. Switch and Data’s presentation of Adjusted EBITDA should not be construed as an implication that its future results will be unaffected by unusual or non-recurring items.

Footnotes:

(1) Rent is accrued as a straight-line expense that incorporates future lease cost escalations. The Deferred rent line item on the Statement of Cash Flows accounts for the difference between cash paid for rent and accrued rent expense for the period.

(2) Stock compensation expense is a non-cash expense that can be found on the Statement of Cash Flows.

(3) Legal expenses for lawsuits brought by landlords for alleged breach of lease agreements that occurred during 2000 or 2001. These expenses are included in the General and Administrative line item of the Statement of Operations.
