The record, newest first
Compass lists an existing 79 MW location in Loudoun County. (Compass Datacenters, Oct. 2026)
Compass began building the first 6 MW building of a campus planned for 75 MW of critical IT load and 500,000 sq ft. (Compass Datacenters, May 14, 2019)
Compass said Loudoun County had approved its rezoning for up to 750,000 sq ft of data centers, after it revised the plan to protect sensitive land along Goose Creek; Data Center Frontier reported a 5-4 board vote and 64 of 106 acres kept open. (Compass Datacenters, Jan. 19, 2018; Data Center Frontier, Jan. 20, 2018)
Conflicts and open questions
- No street address was found in an opened source; the point is placed from the reported location (south of the Greenway by Goose Creek) and is approximate.
- Compass does not say how many buildings are complete. Data Center Frontier reported the site is next to land Google bought for a future campus.
