The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
Meta’s facility sheet describes Rosemount as forthcoming, with the global directory recording a 2024 groundbreaking. Epoch AI estimates the buildings became operational in June 2026 by extrapolating from March satellite imagery; this is not a confirmed operator opening. The construction/commissioning classification remains provisional pending direct confirmation.[1][2][3]
