 Equinix Executes Sale-Leaseback Agreement for Recently Acquired Data
      Center in L.A. Area and Updates Expectations for Financing
                     Washington, D.C. Area Campus

    FOSTER CITY, Calif.--(BUSINESS WIRE)--Oct. 25, 2005--

   Company Also Announces Agreement for Early Termination of Ground
     Lease in San Jose Yielding Substantial Long-Term Cost Savings

    Equinix, Inc. (Nasdaq:EQIX), the leading provider of
network-neutral data centers and Internet exchange services, today
announced that it has entered into a sale-leaseback agreement for the
data center property it recently purchased in the Los Angeles area.
Equinix also has entered into a non-binding letter of intent to obtain
long-term debt financing on Equinix's recently-purchased Washington,
D.C. area data center campus and to amend its ground lease for 39
acres of land in San Jose to allow for early termination of Equinix's
obligations under this lease.
    In September 2005, Equinix purchased a 107,000 square foot
stand-alone data center located in El Segundo, in the Los Angeles
area, for $34.7 million, including closing costs. The Company has now
entered into a purchase and sale agreement dated October 24, 2005, to
sell this data center for $38.7 million and to lease it back from the
purchaser pursuant to a long-term lease. Equinix will realize
approximately $15 million in cash savings over the initial term of the
lease as opposed to having entered into a direct lease with the
previous owner. These savings include a cash benefit on the sale of
the center approximating $3.5 million, net of costs. The
sale-leaseback transaction is subject to certain closing
contingencies. Although there can be no assurance that these
contingencies will be met, it is expected that these conditions will
be removed on or before November 1, 2005 and the transaction will
close before the end of the year.
    In October, Equinix purchased its flagship Washington, D.C. area
data center campus in Ashburn, Virginia for $53.0 million. The Company
drew down $30.0 million of its $50.0 million Silicon Valley Bank
revolving credit line to fund a portion of the purchase price for this
property. The Company has negotiated a non-binding letter of intent to
finance this acquisition with a $60.0 million, 8% mortgage to be
amortized over 20 years. Equinix plans to continue expanding its IBX
operations on the Ashburn campus and has agreed to invest $40.0
million in the property by the end of 2007. This financing is subject
to completion of definitive agreements, and although there is no
assurance that the definitive agreements will be completed, the
Company currently expects the transaction to close before the end of
the year. In addition, Equinix currently intends to list for sale
those buildings that will not be used for its current operations or
expansion plans.
    The Company also announced today that it has entered into a
non-binding letter of intent for the early termination of its San Jose
ground lease. The ground lease, which covers 39 acres, was entered
into in June of 2000 and had a remaining commitment of nearly $100.0
million through 2020. Equinix has determined that there were more
attractive expansion opportunities than building a new center on this
property and requested an early termination of the lease. Under the
proposed terms of the letter of intent, Equinix will pay $40.0 million
over the next four years, commencing January 1, 2006, as well as
certain carrying costs of the property totaling an additional amount
of approximately $1.5 million. This financing is subject to completion
of definitive agreements, and although there is no assurance the
definitive agreements will be completed, the Company currently expects
the transaction to close in January 2006. As a result of the deal,
Equinix will incur a restructuring charge in the range of $35.0 to
$40.0 million in the fourth quarter.
    "The financial strength of Equinix has enabled us to gain
financial control over key strategic properties and to better align
our real estate assets with our long-term expansion objectives," said
Peter Van Camp, CEO of Equinix. "Assuming the completion of these
transactions on current terms, we anticipate significant savings over
the terms of these leases."
