The more than 280 MW of IT load, the MYR12 billion (USD3 billion) investment and the 3,000-plus construction jobs were announced for JHB4 and JHB3 together, so they are not recorded as metrics for this campus alone. AirTrunk's site page states a total capacity without saying whether it is IT load. No construction start or status update after the announcement was found.
