EQUINIX ANNOUNCES PRICING OF OFFERING OF CONVERTIBLE

SUBORDINATED NOTES DUE 2012

Foster City, CA — March 27, 2007 — Equinix, Inc. (Nasdaq: EQIX), the leading provider of network-neutral data centers and Internet exchange services, announced today that it has entered into an agreement to sell $220 million aggregate principal amount of unsecured 2.50% Convertible Subordinated Notes due 2012. Equinix also has granted the underwriters an over-allotment option to purchase up to $30 million aggregate principal amount of additional notes on the same terms and conditions.

Under certain circumstances, the notes will be convertible into Equinix common stock at an initial conversion rate of 8.9259 shares per $1,000 principal amount of notes, subject to adjustment.
