The record, newest first
TierPoint's spec sheet lists more than 140,000 sq ft in total, over 50,000 sq ft of production space and liquid cooling for dense cabinets. (TierPoint, Oct. 24, 2026; TierPoint, Oct. 24, 2026)
Data Center Knowledge reported that Lincoln Rackhouse bought the Marlborough building where TierPoint runs its data center. (Data Center Knowledge, May 4, 2016)
Conflicts and open questions
- The building is owned by a landlord (Lincoln Rackhouse as of 2016 reporting); TierPoint is the operator.
- The TierPoint location web page could not be opened; the address comes from TierPoint's Massachusetts listing and spec sheet.
- Coordinates from the Census geocoder's match for the street address; the building sits next to the Southborough line, but the Census places the address in Marlborough (Middlesex County).
