Equinix finished 2011 with 4,317 customers, excluding smaller clients inherited through the Virtu acquisition in East Netherlands. While looking at customer count may not be necessarily indicative of revenues, the exercise of analyzing this metric may be interesting to see local strengths, as building ecosystems (or communities of interests, as TeleCity calls them) is one of the best ways to ensure the success of a data center, especially if you have magnet customers among them.
Here is a quick look at Equinix’s situation, in general:
The financial vertical represents the largest customer count in New York metro and Chicago, as you might probably expect from a company that hosts 8 of the 11 largest stock exchanges in the world. It is recent news that CBOE is also moving to Equinix’s NY4 facility in Secaucus, making the facility one of the key hubs for trading in the area.
Networks and Enterprises represent the largest customer count in the Washington, DC metro and Silicon Valley, in line what you would probably expect as Equinix’s data centers in these areas represent the most connected hubs on the East and West Coast of the USA.
The financial vertical seems to be the leading force behind Equinix’s London data centers, while Networks represent the most interesting sector in Singapore, where the company has established itself as one of the peering hubs in the whole Asian region.
