This is a proposed or under-construction project. It is not operating capacity, and announced projects do sometimes change scope or fail to proceed.

Capacity: Estimate from a data center listing site. Cleanview project map, read October 7, 2026. The listing does not say what the figure measures.

Working here

We do not publish per-facility headcount, because no reliable public figures exist for these sites and construction announcements are not permanent employment. What we can show is real: open Arizona roles at this operator, gathered from their own job board.

Our own notes

These remarks are Arizona AI's own. They say how this record is counted or what we could not find, so there is no outside page to link.

Arizona AI counts this building as one of the three not yet confirmed online, so it stays with the announced projects until Meta or an official record confirms it.
