zColo adds its 20th site and establishes presence in Chicago

LOUISVILLE, Colo. – October 9, 2012 – zColo, a Zayo Group Company, announces the opening of its data center located at 600 South Federal Street in Chicago’s downtown financial district. The newest zColo facility will provide carrier-neutral colocation and interconnection services to cloud, enterprise, financial, carrier, media and other connectivity-focused customers.

This is zColo’s first location in Chicago, the 3rd largest market in the U.S., home to top global financial institutions, including the Chicago Stock Exchange, the Chicago Board Options Exchange (CBOE) and the Chicago Mercantile Exchange. The Chicago data center will provide access to Zayo’s new Ultra-Low Latency northern route between Chicago and Seattle.

This interconnection-focused data center provides carrier-neutral colocation space of 12,200 square feet and supports up to 200 watts per square foot for high-power density applications. Twenty percent of Phase 1, or 5,300 square feet of raised floor space, is currently pre-leased. The facility features highly redundant power and highly efficient cold aisle containment on the raised floor.

600 South Federal will be home to zColo’s complete set of connectivity options, providing in-suite cross connects, connection to 32 carrier networks in the building through extensive riser assets and expanded metro presence through the recent addition of the Metro Interconnect product providing access to Zayo’s 68,500-mile international network.

Metro Interconnect will offer connectivity to 18 key buildings in the Chicago metro market, allowing customers to maintain a virtual presence across the key carrier hotels and data centers including 350 East Cermak. This will provide customers located at 600 South Federal fast and reliable access to the largest traffic exchange points in Chicago. Customers can establish a physical presence at 600 South Federal to support larger applications and increased power densities, while maintaining a virtual presence at 350 East Cermak through dark fiber cross-connects.

Zayo will be hosting a launch event at 600 South Federal to celebrate the grand opening on October 24th, 2012. For more information, contact Steve Finnerty at
