Each site is one Watermark investigation. The page color says what opens; the campus line is the build on the ground — two different clocks.

← Wiki

Cloud-consumer candidates

29 corridor operations marked cloud-consumer candidates on demand-fit only — each has at least one workload class that hyperscale / edge infrastructure exists to serve. 5 carry a publicly documented cloud relationship. Curated, not corpus-derived; they sit alongside the entity graph.

Demand-fit, not a claim about Google's customers

"Candidate" means an operation whose workloads fit what a hyperscale campus serves — a lead to investigate, not a statement that it is or will be a tenant.

Tier 1 — documented cloud relationship or strong demand-fit
