Data centers in Virginia

About Virginia

Virginia has the second-highest count of listed data centers among US states: 407 facilities, 16 percent of the 2,612 listed in the United States, run by 42 operators in 31 towns and cities. Ashburn has the most with 106, followed by Sterling with 92 and Manassas with 49. Sandston (22), Chantilly (20) and Leesburg (17) come next. The directory's two Virginia markets are Northern Virginia, with 350 facilities, and Richmond, with 33.

Amazon Web Services has the most listings, 131, followed by Digital Realty with 32, QTS with 26 and Equinix with 25. Microsoft has 13. Colocation sites (192) and hyperscale sites (155) make up most of the list, and 324 records have a building outline mapped in OpenStreetMap.

Capacity is published in two measures that should not be added together. Of the 17 buildings with a published IT load, the largest figure is the 96 MW listed for NTT's VA11 Data Center, which is under construction; of the others, CyrusOne's NVA9 in Sterling is the largest at 38 MW. Of the 15 with a published utility supply, Digital Realty IAD39 in Ashburn leads at 120 MW, ahead of IAD40 at 102 MW. By floor area, IAD39 is also the largest listed building, at about 1.0 million square feet.

24 facilities are under construction and 5 are planned, among them CloudHQ's LC5, LC8 and LC11 and Cologix ASH2. 6 facilities hold an Uptime Institute certification, all at Tier III.
