Location

Exact location — MassGIS FY2026 parcel 020-02-003 / LOC_ID F_355950_2900713. No coordinate is asserted.
Physical scale
MassGIS FY2026 assessor fields report BLD_AREA 91,700 square feet, LOT_SIZE 1.66 acres, and YEAR_BUILT 2012 for parcel 020-02-003. These are assessor fields for this parcel/building, not white-space area, commissioned IT area, a campus total, or a count of the owner's other parcels.

What the sources support

UMass Amherst Information Technology reported that the MGHPCC data center's computer floor and services lost power on April 19, 2026, that power was restored, and that Unity returned to service that afternoon. A Massachusetts government release separately describes MGHPCC in Holyoke as a research data center serving researchers. This supports operating status on the dated service event, not real-time continuous operation, every system, or full utilization on the retrieval date.
