Southern Telecom Joins QTS’ Expanding Connectivity Ecosystem in Atlanta

QTS Realty Trust (NYSE: QTS), a leading provider of software-defined and mega scale data center solutions, today announced that Southern Telecom, Inc. (STI), a subsidiary of Southern Company (NYSE: SO) has deployed its dark fiber network in QTS’ Atlanta-Metro data center campus.

As a leading dark fiber provider, STI expands QTS’ ability to provide multiple dark fiber paths across the southeast region. STI’s Atlanta to Jacksonville, FL fiber route is an ideal option for connection with subsea cable paths requiring connection to Atlanta and beyond.

QTS recently opened Atlanta-Metro Data Center 2 (DC2) featuring 240,000 square feet of data hall space and 72 megawatts of power capacity designed for large-scale enterprise and hyperscale colocation deployments. Atlanta-Metro DC2 was constructed utilizing QTS’ modular Freedom data hall design that caters to the most sophisticated buyers in the industry. The addition of STI’s dark fiber brings the total number of dark fiber providers in QTS’ Atlanta-Metro data center campus to five.

QTS Atlanta-Metro DC2 sits adjacent to the Company’s flagship Atlanta-Metro Data Center (DC1) on a 95+ acre site that now encompasses 200+ megawatts of available utility capacity fed from two of the largest pre-positioned, data center owned substations in the country. These substations enable QTS to deliver the lowest cost of power to its customers in the southeast data center market. Upon full development, the Atlanta-Metro campus is expected to support more than 275 megawatts of power capacity.

“We are pleased to be part of QTS’ Atlanta-Metro data center campus,” said Barry Navarre, Southern Telecom Business Development Manager. “Southern Telecom’s dark fiber and strategic long-haul routes will help QTS provide their customers with massive scale, operational maturity, speed to market and a premium customer experience.”

“Southern Telecom is an important addition to the expanding roster of networks available at our Atlanta campus,” said Sean Baillie, Executive Vice President, Connectivity Strategy, QTS. “We continue to expand our already dense connectivity ecosystem providing in-building access to network services required by enterprises, government entities and hyperscale customers We welcome Southern Telecom as our newest network partner.”
