              Equinix to Purchase Its Flagship Silicon Valley IBX

    FOSTER CITY, Calif.--(BUSINESS WIRE)--Feb. 7, 2007--Equinix, Inc.
(NASDAQ:EQIX), the leading provider of network-neutral data centers
and Internet exchange services, today announced an agreement to
acquire its flagship Silicon Valley property for $65.0 million.

    The Company intends to finance the majority of the cost of the
acquisition, following an initial $6.5 million deposit. Although the
closing date is yet to be determined, it will occur no later than
November 2007. Equinix's flagship Internet Business Exchange(TM)
(IBX(R)) center in San Jose is one of four IBXs currently occupied by
the Company in the Silicon Valley area.

    "Like the purchase of our Washington DC area campus in 2005, we
have acquired our Silicon Valley IBX, a strategic interconnection hub
on the West Coast. The acquisition will enable us to gain long-term
control of this strategic IBX center," said Peter Van Camp, chairman
and CEO, Equinix. "Furthermore, this deal may provide us with greater
options in potentially expanding our IBX footprint in this important
market to meet the growing demand for our colocation and network
interconnectivity services."
