Four thousand records, three sources, one registry — measured against a frozen benchmark.
No single public source knows where America's data centers are. The best one lists 780 facilities. Others hold thousands more under different names, at differently formatted addresses, with overlapping and contradictory coverage. Fusing them is the only route to a usable picture — and fusing them badly is worse than not fusing them at all.

A resolver fuses Compute Atlas, PeeringDB and OpenStreetMap into one registry with per-record provenance and per-field lineage: 4,017 source records resolve to 3,319 distinct facilities, collapsing 698 duplicates — 4.3 times the coverage of the best single source.
A frozen, stratified, hand-labelled benchmark of 90 candidate pairs, each adjudicated against the raw source records with the reasoning written down, scores the current resolver at 100% precision and 95.5% recall. The registry takes an explicit position on carrier hotels: the building is the unit of record, and tenants are captured separately rather than merged into it.
