Exhibit 99.1


             Equinix to Purchase Its Flagship Washington, D.C. Area
            Data Center Campus; Company Ahead of Schedule on Closing
                of Sale-Leaseback of New Los Angeles Area Center

     FOSTER CITY, Calif.--(BUSINESS WIRE)--Oct. 6, 2005--Equinix, Inc.
(Nasdaq:EQIX), the leading provider of network-neutral data centers and Internet
exchange services, today announced an agreement to acquire its flagship
Washington, D.C. area data center campus in Ashburn, Virginia for $53.0 million.
The company also announced that it expects to close the sale-leaseback of its
newly acquired Los Angeles area data center within 30 days, ahead of its
previously announced target of year-end.
     Equinix's flagship Internet Business Exchange(TM) (IBX(R)) center in
Ashburn is part of a 32.6 acre campus that totals 461,700 square feet located in
the Dulles Corridor that is home to many of the region's technology companies.
Equinix currently occupies three of the six buildings on the campus, including
two fully built-out IBXs and a third available for expansion. The total campus
is 95% leased. Equinix intends to sell those buildings that will not be used for
expansion, and the company will evaluate opportunities to secure long-term
financing on the retained buildings, either in the form of sale-leaseback or
mortgage financing, by year-end. Equinix also leases a fourth building on a
nearby campus that was opened as a part of the company's Washington, D.C. area
expansion in December 2004.
     Equinix also announced that it is ahead of schedule in the closing of the
sale-leaseback of its Los Angeles area center in El Segundo. The company
originally purchased the property for $34.5 million in September of this year
and is currently in negotiations with multiple parties to sell the center for
$36.0 - $40.0 million. Equinix expects to close the transaction within 30 days.
     "With the announced sale of the Ashburn campus, we saw an opportunity to
secure our flagship IBX center as well as to acquire contiguous expansion space
to position ourselves for further growth in one of our strongest markets," said
Peter Van Camp, CEO of Equinix. "Given the tremendous interest we have received
in the planned sale-leaseback of our recently acquired Los Angeles area center,
we are confident there is a great opportunity to obtain attractive long-term
financing for this strategic Washington, D.C. area property as well."
     The purchase of the Ashburn, Virginia campus is not expected to have a
negative impact on the company's previously issued guidance on quarter and
year-end revenue and EBITDA. Absent this transaction, Free Cash Flow guidance
for the year would also not be negatively impacted. Depending on the nature of
the financing used for this property, the company will update Free Cash Flow
guidance on Equinix's third quarter earnings conference call.
