DayOne's October 5, 2026 SEC filing reports that its Thailand market had 73 MW of capacity in service and 47 MW under construction as of September 20. The filing defines in-service capacity as ready-for-service, fitted-out IT capacity, not measured power draw. These are Thailand-market totals, without an explicit allocation between CTP1 and CTP2, and are separate from the 300 MW power envelope and longer-term 1 GW ambition. DayOne is building a two-site Chonburi platform anchored by CTP1 and prospective CTP2, with a long-run 1 GW power ambition. DayOne Chonburi Tech Park Program is located in Amata City Chonburi, Chonburi, TH and is a program with development and market-level service progress reported.
