56 Marietta Street Data Center, Georgia

Possibly the Southeast’s largest concentration of telecommunication companies is housed in this former office building in downtown Atlanta, managed by Digital Realty (formerly Telx). It is a major connection point on the fiber optics traveling between New York and Florida. Nearby is 180 Peachtree Street, a regional data center and internet exchange point, mostly managed by Level 3 Communications, as Atlanta 2 Gateway.
