FOR IMMEDIATE RELEASE

EQUINIX GAINS ADDITIONAL $10 MILLION INVESTMENT; ACCELERATES

CASH FLOW POSITIVE FROM OPERATIONS PROJECTION TO THIRD QUARTER

2003

Foster City, CA—April 30, 2003—Equinix, Inc. (Nasdaq: EQIX), the leading provider of network-neutral data centers and Internet exchange services, today announced that Crosslink Capital has entered into definitive agreements for a $10 million investment in Equinix. Crosslink is a private equity investment firm that focuses on investing in software, services and semiconductor companies. The Crosslink investment combined with last year’s $30 million investment from Singapore Technologies Telemedia Pte Ltd (ST Telemedia) completes the funding goal of $40 million announced late last year and provides the company with additional funds to assure a comfortable cash position until profitability.

As a part of the transaction, which is targeted for completion in June, Gary Hromadko, Venture Partner, Crosslink Capital will join the Equinix Board of Directors. The closing of the transaction and its timing are subject to the approval of Equinix’s stockholders, SEC clearance and the satisfaction and waiver of other closing conditions. A proxy statement will be filed today with the SEC to seek stockholder approval of the shares to be issued in connection with the transaction. Citigroup Global Markets acted as financial advisor on the transaction.

“Equinix has many of the qualities that we look for in an investment opportunity: a position of market leadership, strong customer traction with well-respected companies, a demonstrated track record of success, and the vision, management team and financial stability to continue as a long-term leader,” said Gary Hromadko, Crosslink Capital.

“Over the past six months, Equinix has transformed its financial standing,” said Peter Van Camp, CEO of Equinix. “The investments and cash that Equinix acquired at the end of last year allowed the company to significantly reduce outstanding debt and strengthen the balance sheet. With this new investment, Equinix will significantly increase operating cash reserves to a comfortable level for the long run. Our improved financial position and growing market share combined with continued strong execution gives us the confidence to accelerate our profitability goals to becoming cash flow positive from operations within the third quarter of this year—a tremendous achievement in the face of an complex international integration effort and a challenging market.”
