IAD40 is a Digital Realty colocation building at 44372 Round Table Plaza (Building M) in Ashburn, Virginia, in the Dulles Tech Corridor of Northern Virginia. It is a two-storey structure of 223,500 sq ft (20,750 sqm) set within a secured site that the operator says has nearly 3 million sq ft of land available for future expansion, and it sits close to Digital Realty's Digital Ashburn campus. The published resilience figures are N+1 UPS redundancy and N+2 cooling redundancy, with CCTV retained for 90 days and biometric or photo-badge access control. Listed compliance covers SOC 2, SOC 3, PCI-DSS, ISO 9001, ISO 14001, ISO 27001 and NIST SP 800-53, and the sustainability section lists Energy Star and 100% renewable energy. Digital Realty positions the site for large-scale deployments, but it does not publish an IT power capacity, rack count, opening year or maximum density for IAD40, so those values remain empty.
