US wholesale data center giant DuPont Fabros has chosen Sidera Networks to provide fiber connectivity for its recently completed data center in Ashburn, Virginia.

Sidera was the first provider to be connected to the new facility (AC6), the connectivity company said Thursday. The company said the deal would be critical to the data center’s customers that need low-latency connectivity and diverse routes between Asburn and the New York City metro.

Clint Heiden, Sidera President, added that the company can “bypass both Manhattan and Washington, D.C., to avoid network congestion points”, for customers that use the Ashburn-New York metro link.

Vinay Nagpal, director of carrier relations at DuPont Fabros, confirmed that the wholesaler chose Sidera because of its diverse low-latency connectivity out of the Ashburn area. The deal expands the relationship between the two companies. Sidera already serves another DuPont Fabros data center in Ashburn, as well as its facilities in New Jersey and Reston, Virginia.

DuPont Fabros has completed Phase I of AC6, which provides 13MW of critical load, according to the company’s website. This is the fourth operational facility at the company’s massive Ashburn campus.
