## Summary

[Microsoft](/zh/entity/microsoft) has wired its [Fairwater](/zh/entity/data-centers) sites in Wisconsin and Atlanta into
what it calls its first "AI superfactory", two facilities joined by a dedicated AI
wide-area network of optical fibre so multiple buildings train one model in tandem rather
than each running separate jobs. The Atlanta Fairwater, online since October 2025, is a
two-story design carrying hundreds of thousands of [Nvidia](/zh/entity/nvidia) GB200 and GB300 GPUs, ~140kW
per rack and ~1,360kW per row, and, unusually, no UPS or backup gen-sets. Microsoft
frames the WAN-linked clusters as cutting model-training time "from months to weeks." The
build sits inside Microsoft's ~$190bn 2026 [capex](/zh/n/hyperscaler-capex-725bn-2026) program.

## By the numbers

- 2, Fairwater sites (Wisconsin + Atlanta) linked into one training fabric.
- ~140kW / ~1,360kW, power per rack / per row at Atlanta.
- Hundreds of thousands, Nvidia GB200/GB300 GPUs across the network.
- Oct 2025, Atlanta Fairwater began operating.

## Why it matters

The "superfactory" is a structural shift: AI training is becoming multi-site, with grid
and fibre, not a single building, as the binding constraint. Dropping UPS and gen-sets
trades conventional reliability for density and speed, a template others will copy.

## What to watch

- Whether more Fairwater sites join the WAN fabric and where they site (power-led).
- Reliability outcomes from the no-UPS/no-gen-set design under real load.
- Local grid and water permitting at each Fairwater campus.
