What the source record says
State government Tier II data center, leased from Pfizer for $1 a year in Building 230 of Pfizer's Groton research campus under a 2014 agreement. It serves roughly 50,000 state personnel and pairs with a Springfield, MA site. The contractor's fast-track renovation covered 9,000+ sq ft, including raised floor, electrical work and four replacement CRAC units. Coordinates are a Census geocode of the Pfizer Groton campus address on Eastern Point Road, not Building 230, so precision is approximate and no street is recorded. Not the Pfizer or NE Edge hyperscale proposals.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.
