It has also been named the nation’s 2nd most wired city, and as the most favorable U.S. city for data centers. Ranking in the top 10 as an “American City of the Future,” by FDI Magazine, Atlanta has a reputation as a well-tuned economic engine, and as one of the crown jewels of the Southeast.

Atlanta, 56 Marietta Street data centre (ATL1)
The Southeast’s largest concentration of telecommunications companies can be found at Digital Realty’s 56 Marietta Street data center facility. Atlanta is a major interconnection point between Florida and New York and Digital Realty’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.

Digital Realty 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.
