56 Marietta is an Interconnection Hub:

56 Marietta is the primary Interconnection building in Atlanta. In fact, the nearest buildings that could rival 56 Marietta's network density is the Equinix campus in Ashburn, Virginia (640 miles), The Nap of the Americas in Miami, Florida (660 miles), 350 E Cermak in Chicago, Illinois, or the Infomart in Dallas, Texas (780 miles).

Because of the building's size and Interconnection density, other colocation companies call 56 Marietta home, including Level3, Cogent, Colocrossing, and Equinix (former Switch and Data's facility.)

The building was acquired as part of the Telx acquisition in 2015.
