The book’s note
Promised ‘online in early 2026’ (18 Sep 2025), read as 31 March. Epoch dates the first building operating on 16 April 2026, 16 days late on that reading; Microsoft’s chief executive called it six weeks ahead of schedule. 2,263 MW is Epoch’s estimate, not Microsoft’s figure. Slippage matrix row 21. Status word aligned with the book’s August 2026 compilation’s table of promised dates at rev 589 (6 Oct 2026): missed if ‘early 2026’ means the first quarter; called six weeks early by its chief executive.
