The popular social-networking site for dating Zoosk has grown to the point of requiring more than retail colocation space.

Silicon Valley data center provider Fortune announced Wednesday that the self-described “romantic social network” has signed up for its turn-key wholesale data center solution in San Jose, California, migrating from a retail colocation facility.

Zoosk co-founder and CEO Shayan Zadeh said the company explored “all available options” and found Fortune to be the best fit for its requirements. “Their turn-key option meant that we could get all the advantages of a wholesale data center while giving us the simplest solution,” Zadeh said.

“We valued their design to support our IT infrastructure, and are confident they can support our fast-paced growth.”

San Francisco-based Zoosk says it has more than 50m users in more than 60 countries. The service is available in 20 languages.

The company has both free and paid premium membership options. It also provides a third-party dating application on other social networks, including Facebook, MySpace, Hi5, Bebo and Tagged.

Zoosk is the first customer of Fortune’s turnkey data center product, where the company provides a fully built-out data center space, complete with a raised floor and all necessary power and cooling infrastructure.

In October 2011 Fortune announced it would expand beyond its home base in the Silicon Valley with a 7.8MW data center build in Hillsboro, Oregon (near Portland).
