Item 1.01. Entry Into A Material Definitive Agreement.

     On October 3,  2005,  Equinix,  Inc.,  a Delaware  Corporation  ("Equinix")
entered into a definitive purchase and sale agreement  ("Agreement") with Trizec
Realty,  LLC, a California limited liability company  ("Seller").  The Agreement
governs the  purchase  by Equinix of an  office/warehouse  complex  known as the
Beaumeade Business Park ("Park") located in Ashburn, Virginia. Equinix purchased
the entire  32.6-acre  Park  containing  six  buildings,  within  three of which
Equinix  is  already a tenant.  The total  rentable  square  feet of the Park is
approximately  461,700  and it is  currently  95% leased.  Equinix  posted a $10
million  deposit  upon  entering  into the  Agreement,  which is  non-refundable
subject to Seller satisfying certain conditions prior to close. The deposit will
be applied  towards  the  purchase  price at  closing.  The  purchase  price was
determined through negotiations between Equinix and Seller, and is approximately
$53 million  dollars to be paid in cash at closing,  which is scheduled to occur
on or before  October 18, 2005.  Equinix  will  continue to operate our existing
data centers within the Park.  Equinix intends to sell those buildings that will
not be used  for our  expansion,  and  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.  Other than the  previous
landlord/tenant  status,  there is no material  relationship between Equinix and
Seller.

             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.
