Digital Realty IAD39 (Round Table Plaza)

With more than one million square feet under one roof, IAD39 at 44274 Round Table Plaza is the largest building on Digital Realty's fifteen-building Northern Virginia footprint. The facility sits in Ashburn's Data Center Alley, the densest colocation and interconnection market in the world, where Digital Realty serves over 200 customers and more than 130 cloud and network providers across the metro. The cooling plant is configured to 2N+1 redundancy, and the campus certification portfolio spans SOC 1/2/3, PCI DSS, NIST SP 800-53 and ISO 27001, 9001, 14001, 22301 and 50001. As part of PlatformDIGITAL, tenants can pair large wholesale footprints in IAD39 with ServiceFabric interconnection and access to the wider Ashburn ecosystem. The building suits hyperscale and large enterprise deployments that need contiguous capacity in Northern Virginia rather than retail cabinets, with room to scale across adjoining Digital Realty sites in Ashburn, Sterling and Reston.
