SCHEDULE 13G
This Amendment No. 2 (“Amendment”) to Schedule 13G (the “Schedule 13G”), relating to shares of common stock, par value $0.001 per share (the “Common Stock”), of Equinix, Inc., a Delaware corporation (the “Issuer”), is being filed with the Securities and Exchange Commission (the “Commission”). This Amendment is being filed on behalf of TCS Capital GP, LLC, a Delaware limited liability company (“TCS GP”), and Eric Semler the principal of TCS GP.
This Amendment relates to shares of Common Stock of the Issuer purchased by Eric Semler and TCS GP for the accounts of (i) TCS Capital, L.P., a Delaware limited partnership (“TCS Capital”), (ii) TCS Capital II, L.P., a Delaware limited partnership (“TCS Capital II”), and (iii) TCS Capital Investments, L.P. a Cayman Islands exempted limited partnership (“TCS Offshore”). TCS Capital holds 62,203 shares of the Common Stock, TCS Capital II holds 340,330 shares of the Common Stock, TCS Offshore holds 688,511 shares of the Common Stock. TCS GP acts as general partner to each of TCS Capital, TCS Capital II and TCS Offshore; and Mr. Semler, as manager of TCS GP, controls the investment decisions of TCS GP.
This Amendment is being filed to amend and restate Items 4 and 5 as follows:
Item 4 Ownership.
  (a)  
TCS GP (as the general partner of TCS Offshore, TCS Capital II, and TCS Capital) is the beneficial owner of 1,091,044 shares of Common Stock, and Eric Semler (as the principal of TCS GP) is the beneficial owner of 1,091,044 shares of Common Stock.
 
  (b)  
TCS GP is the beneficial owner of 3.0% of the outstanding shares of Common Stock. Eric Semler is the beneficial owner of 3.0% of the outstanding shares of Common Stock. These percentages are determined by dividing 1,091,044 and 1,091,044, respectively, by 36,293,262, the number of shares of Common Stock issued and outstanding as of September 30, 2007, as reported in the Issuer’s most recent Form 10-Q filed November 2, 2007.
 
  (c)  
As the general partner of TCS Offshore, TCS Capital II and TCS Capital, TCS GP has the sole power to vote and dispose of the 1,091,044 shares of Common Stock beneficially owned by it. As the principal of TCS GP, Eric Semler has the sole power to vote and dispose of the 1,091,044 shares of Common Stock beneficially owned by him.
Item 5 Ownership of Five Percent or Less of a Class.
If this statement is being filed to report the fact that as of the date hereof the Reporting Persons have ceased to be the beneficial owners of more than five percent of the class of securities, check the following þ.
