SDC Ashburn is Sabey's 38-acre Intergate campus at 21741 Red Rum Drive in Loudoun County, planned at 85 MW of critical capacity and 645,000 sq ft of mission-critical space across three buildings, fed diversely from an onsite 300 MW substation on Dominion Energy's ring transmission network. Building C opened in 2017 with 7.4 MW and Building B followed with 23 MW, together putting more than 36 MW in service. Building A, the third and final phase, broke ground on 25 June 2025 as a three-story building delivering 18 MW on opening in 2026 and 54 MW at completion. The operating buildings average an annualized PUE of 1.35 on evaporative and economizer cooling. Five networks meet in the campus meet-me rooms, with Cogent, Crown Castle, Fiberlight, PacketFabric and Zayo on net. SOC 1 Type 2, SOC 2 Type 2, ISO 27001 and PCI DSS audits cover the campus, and modular halls, build-to-suit and powered shell are all sold on it.
