The ATL1 - Telx Data Center

56 Marietta St Atlanta, Georgia 30303

The Southeast's largest concentration of telecommunications companies can be found at Telx's 56 Marietta Street data center facility. Atlanta is a major interconnection point between Florida and New York and Telx's downtown facility sits on top of most of this fiber. As a result, businesses have more choices for carrier-neutral interconnection, colocation and data center access from this location compared to any other in the region.

Telx® acquired this 160,000 sq.ft. interconnection and colocation facility in 2004 and today is the building's interconnection area operator. ATL1 complies with or exceeds International Telecommunication Union (ITU) industry standards.
