  Equinix to Build out New IBX Center Within Recently Acquired Washington, D.C.
 Area Campus; Company Also Announces Plans for Further Expansion in the Chicago
                 Metro Area; Secures Building for Due Diligence


     FOSTER CITY, Calif.--(BUSINESS WIRE)--Feb. 8, 2006--Equinix, Inc.
(Nasdaq:EQIX), the leading provider of network-neutral data centers and Internet
exchange services, today announced that the company will build out a new center
within its Washington, D.C. area campus to further expand its Washington, D.C.
area Internet Business Exchange(TM) (IBX(R)) center. Equinix also announced that
it intends to expand in the fast growing Chicago metro area and has secured a
potential site for future expansion.
     Based on the success of Equinix's most recent expansion in the Washington,
D.C. area in 2004, continued strong demand in the market, and strong financial
returns, the company has decided to build out an existing structure on the
campus that it announced the acquisition of last year. The expansion will add
approximately 1,500 - 1,700 cabinets immediately adjacent to Equinix's existing
IBX.
     Equinix's Washington, D.C. area campus is located in the Dulles Corridor
and is home to many of the region's technology companies. The campus totals
461,681 square feet and houses over 120 networks, making it one of the richest
IP network interconnection points in the U.S. Equinix will build out one of the
undeveloped buildings as a part of this new initiative, investing approximately
$50.0 to $55.0 million of capital expenditures, of which approximately $40.0
million is expected to be incurred in 2006. The center will feature an updated
design that will enable Equinix to expand its capacity and support the increased
power and cooling demands of customers. Equinix intends to open the new center
for customers in early 2007.
     Equinix has also announced a decision to expand its presence in the Chicago
metro area. Based on the results of a comprehensive nationwide demand study that
Equinix conducted in 2005, this expansion will support enterprise demand in the
Chicago area, and it will complement the strength of the Equinix Financial
eXchange customer base in Equinix's existing Chicago IBX center located in the
downtown area. A new center would be interconnected to Equinix's downtown center
through redundant dark fiber links managed by Equinix, enabling new customers in
each center to have direct access to the more than 75 networks already operating
in Equinix's downtown IBX center.
     To support this decision, Equinix has secured a potential site for $9.75
million, payable upon closing, in order to conduct a full evaluation of the
property and the financial returns associated with a potential definitive
purchase. The building is approximately 228,000 square feet. The agreement is
subject to numerous closing conditions, including the satisfactory completion by
Equinix of a comprehensive due diligence review of the property. As part of the
evaluation process, Equinix is considering several partnering and financing
options for building out this center and is also evaluating options to build out
this center in a phased approach.
     "Demand and pricing trends in these markets make new green field builds
financially attractive for Equinix again," said Peter Van Camp, CEO of Equinix.
"Today's announcement is a continuation of our ongoing expansion program to
enable us to grow the company with the potential to generate annual revenues of
$500 million over time."
