CREWS LINKED TWO DATA CENTERS 700 MILES APART INTO A SINGLE MACHINE , AND A CLOUD GIANT SAYS THE FIBER LINK CUTS AI TRAINING TIME FROM MONTHS TO WEEKS

What happened: Microsoft connected its Fairwater data centers in Wisconsin and Atlanta, 700 miles apart, with a dedicated fiber-optic AI WAN so they run as one machine for AI training. Key numbers: Wisconsin site spans 315 acres, 1.2 million sq ft, three buildings. Why it matters: Microsoft says the link cuts AI training from months to weeks and claims 10 times more performance than today's fastest supercomputer, though it has published no official GPU count, megawatt figure, or benchmark, and the claim is not independently verified.
