The occasion

Microsoft Build 2026 keynote, 2 June 2026.

Context

Presenting Microsoft's 'community-first' AI infrastructure plan at Build 2026, Nadella said the newest data centers use a cooling loop filled once, and likened a year of water use to a single restaurant's. The design is so far in place at the Fairwater campus in Wisconsin; no keynote video was fetched.

Crowd reaction

Critical commentary

Critical commentary: Analytics India Magazine says critics call the reassurance premature because most data centers still use evaporative cooling, and reports protesters outside Build; Tom's Hardware calls the claim 'striking' against historic hyperscale water use and notes it applies so far to one campus.
