The Telx Group, a New York City-based data center operator, has filed for an initial public offering that could see it raise as much as $100 million from the public markets. The last major data center operator to go public was RackSpace (s RAK), and that was back in 2009. With the demand for data centers and Internet services on an upswing, Telx’s attempt to go public is very timely.

The company is well known for owning being a primary lease holder at 60 Hudson Street, an iconic wired carrier hotel in Manhattan where more than 250 networks converge. Owned by private equity firm GI Partners, its other assets include The Planet and EV1 Servers.

Telx has 15 data centers with about half a million square feet of data center space. The company had revenues of $98.3 million in 2009 and net losses of $9.9 million. Telx, which also provides global interconnection and co-location services, has about $130 million in debt. The IPO is being underwritten by Goldman Sachs & Co. and Deutsche Bank Securities. Telx has applied to trade on the Nasdaq market under the ticker TELX.
