Equinix DC4 occupies 21691 Filigree Court, a one-storey reinforced-concrete hall with 60,590 sq ft of colocation space on the Ashburn campus, and shares with DC5 the strongest electrical design of the four Filigree Court IBXs: N+2 UPS, N+1 generators carrying 30+ hours of fuel at full load, and N+20% cooling redundancy. Cabinets start at a 5 kVA minimum on 120V/208V distribution, with free cooling and hot/cold aisle containment on the floor. The building stands above the 500-year flood elevation and is protected by double-interlock pre-action suppression with VESDA detection. Its compliance list runs to SOC 1 and SOC 2 Type II, ISO 27001, 22301 and 9001, PCI DSS, HIPAA and NIST 800-53/FISMA High. DC4 falls inside the AWS Direct Connect DC1–DC6, DC10–DC12 range and the Google Cloud Interconnect DC1–DC15, DC21 range, and sells Secure Cabinet Express, Private Cage, Fiber Connect, Fabric and Equinix Internet Exchange from a single floor.
