This page compares nine data-centre and cloud operators in Malaysia. The firmest capacity figure is DayOne’s: 789 MW of IT capacity in service in Johor on 20 September 2026, from its US listing prospectus (DayOne, SEC Form F-1, 5 Oct 2026). AirTrunk has announced more than 700 MW of IT load across four Johor campuses (w.media, 30 Apr 2026), and Bridge Data Centres lists over 1.8 GW of IT capacity, built and planned together (Bridge Data Centres, 18 Jul 2026).
Google, AWS and Microsoft publish investment pledges (US$17 billion in two pledges, about US$6.2 billion and US$2.2 billion) but no megawatts for any Malaysian site (Google, 4 Nov 2026) (MIDA, 22 Aug 2024) (Microsoft, 2 May 2024).

How should these figures be read?
- IT load or total power: DayOne, Bridge and AirTrunk state IT capacity. YTL’s broker figures do not say which.
- Built or planned: DayOne splits in-service from under-construction. Bridge’s 1.8 GW mixes both.
- Pledge or spending: every investment figure here is a pledge, plan, loan or project value. None is a published figure for money already spent.
- Who says it: a prospectus filed with a regulator carries legal liability; a marketing page, a broker’s note and a trade-press figure with no source do not.
What is not public
We could not confirm these from a published source as of 11 November 2026. Do not assume them:
- Megawatts for any Google, AWS or Microsoft site in Malaysia
- Customer names at DayOne, YTL Power and AirTrunk, other than those in the profiles
- Contracted grid power by operator
- Money actually spent to date by any operator
