Customer QA

Why is this merger good for me, the customer?

The mergers leverage clear synergies between the businesses and create the largest global network neutral Internet exchange services company. Here is why this is important to customers:

Immediate extended reach: Leveraging the established infrastructure of all three companies gives customers immediate access to additional key business markets and new services.

One-stop Internet infrastructure services: Our extended geographic reach encompassing 14 Internet exchange (IBX) centers in six countries will provide customers with a single source—one vendor, one bill, consistent quality—solution for your Internet exchange and IT infrastructure services requirements in two major regions.

Stable financial base: This agreement results in a financially strengthened business with a healthy balance sheet for future business growth and a larger revenue base with the

potential for strong EBITDA growth. With the completion of this deal, the new Equinix will be well positioned to continue to execute on the strengths of each of the businesses, build a profitable company, and most importantly, continue to provide superior services and support to our customers.

What are the day-to-day changes I should expect in my dealings with Equinix, i-STT and Pihana?

In the short term operations will run business as usual for all three companies. Over the long-term, we expect to bring additional service and value to customers through our expanded global reach and service set.

Will there be any interruptions to my services as a result of this transition?

No. We expect this transition to be seamless to your operations. Once the mergers are completed, which is targeted for completion at year-end, we will provide additional details on the integration, services, and support. We are planning carefully to make this integration as easy and convenient as possible for our customers, with no impact to operations.

Whom do I call for support?

Please continue to contact your existing support representatives.

Whom do I call to order new services for any of the 14 IBXs?

Until the close of the transaction, your sales representative can assist with any needs you may have in the U.S. and Asia-Pacific and refer you to the appropriate contacts at each respective company to handle your requirements.

Who is the new management team?

Current Equinix management will continue to lead the merged company under the leadership of CEO, Peter Van Camp. The head of the Asia-Pacific region, reporting to Peter Van Camp, will be named at a later date.

Will all existing Equinix, Pihana and i-STT services continue to be supported post-merger?

In addition, the company features network-neutrality in all locations, providing customers with the best choice of networks for the greatest operational flexibility, performance, and cost-efficiencies.

Will any new services be offered as a result of the merger?

Yes. Equinix will be able to provide customers of all three companies with a variety of Internet exchange and IT infrastructure services in additional locations in the US and Asia-Pacific, giving customers a single source—one vendor, one bill, consistent quality—solution.

Our service now extends to six countries and fourteen IBX centers, access to more than 100 network service providers and includes a broadened portfolio of Internet exchange and value-added services.

Panther and iJaguar both offer managed services. Will you continue to offer these services?

In addition, the company will remain network-neutral in all locations, providing customers with the best choice of networks for the greatest operational flexibility, performance, and cost-efficiencies. Equinix will continue to offer customers a choice of services providers in all locations.

What is the status of Equinix’s Interxion partnership in Europe?
