Item 7.01. Regulation FD Disclosure

On July 8, 2009, several investors contacted the Company to inquire about a rumor in the market regarding “speculation about Equinix’s accounting.” It is the Company’s policy to decline to comment on unsubstantiated rumors. However, one of the Company’s directors was contacted by an investor to respond to this rumor and the director responded that he was not aware of any facts supporting the rumor. Accordingly, the Company is making this filing in order to inform all investors that the Company is not aware of any undisclosed accounting matters affecting the Company.
