The following is a letter distributed by Equinix, Inc. to its customers on October 2, 2002:
Dear Equinix Customer,
I’d like to take a moment to update you on a significant development at Equinix.
I’m pleased to inform you that today, Equinix announced an agreement to merge the assets of i-STT, the Internet infrastructure service subsidiary of Singapore Technologies Telemedia Pte Ltd (ST Telemedia), and Pihana Pacific, a leading provider of neutral Internet exchange data center services and managed e-infrastructure services in Asia-Pacific, into Equinix’s core Internet exchange services business. As a result of merging these businesses into Equinix, we will become the largest global network neutral Internet exchange services company, with great benefits to our customers.
Equinix will leverage the established infrastructure of all three companies. Once the merger is completed, you will have immediate access to comprehensive network exchange and e-business infrastructure services internationally, including access to more than 100 network service providers within network-neutral facilities in six countries. The synergy resulting from these mergers will enable us to focus on delivering the core Internet exchange and infrastructure services that customers expect from us—services which dramatically improve the performance and reliability of all network and Internet operations
As part of the merger announcement, we have also announced plans to substantially reduce our financial obligations, including the retirement of more than $130 million of debt. In addition, we announced that Singapore Technologies Telemedia Pte Ltd has made a $30 million investment in Equinix. This investment, coupled with the merger, result in a financially strengthened business with a healthy amount of cash on the balance sheet for future business growth and a larger revenue base.
The integration of i-STT and Pihana into Equinix highlights our commitment to be the leading provider of network-neutral Internet exchange services in Asia Pacific and the United States. The new Equinix’s geographic reach will extend to six countries, and 14 Internet exchange centers encompassing over a million square feet of network-neutral, Internet exchange space.
We are targeting to complete the transaction by the end of 2002. Meanwhile Equinix will continue to operate business as usual. Once the merger is completed, we will provide

additional details on the integration, services, and support as we progress. We are planning carefully to make this integration as easy and convenient as possible for our customers.
We will be regularly updating our website to keep you informed about the merger progress. Please visit us at for more information or contact your sales representative with any questions.
Thank you for your business. We look forward to better serving your Internet exchange and IT infrastructure needs and to continue delivering the superior services and support that you expect and deserve with the combined resources of the new Equinix.
