Serverfarm bought the Quantum Drive properties from Legacy Investing and Element Critical. (DatacenterDynamics, Feb. 2026)
Conflicts and open questions
- power is not reported and the site is 14.4 acres, under the 100-acre floor used when power is unknown.
- The site is about 0.9 miles from the Tysons Corner Metro entrance, inside the county's 1-mile buffer, which the applicant asks to reduce.
- An existing data center at 7790 Quantum Drive in the same complex is described by DCD as Equinix DC7; whether Serverfarm operates any existing data center here was not confirmed.
