Why is Singapore colocation so constrained?
In 2019 Singapore imposed a moratorium on new data centre builds to manage power consumption and emissions. The moratorium was lifted in 2022 under the Data Centre Call for Applications (CFA) framework — a controlled-release model where operators must apply for capacity and meet strict green energy and efficiency criteria. The result: vacancy of approximately 1.4%, the lowest in APAC, and lease rates among the highest in the region.
What is DC-CFA2?
DC-CFA2 is the second Call for Applications, launched on 1 December 2025. It releases at least 200 MW of new data centre capacity through approved operators. Application window closes 31 March 2026. Approved operators must source at least 50% of power from approved green energy pathways, achieve 1.25 PUE at full load, and meet stringent economic contribution criteria.
Who are the major Singapore operators?
Equinix (SG1-SG5), Digital Realty (SIN10-SIN12), ST Telemedia Global Data Centres, Keppel DC REIT, Singtel and AirTrunk. AirTrunk's SGP2 is one of the largest upcoming facilities at 70+ MW. ST Telemedia GDC, as a Singapore-anchored operator, has particularly strong domestic ecosystem positioning.
How does Singapore compare to Tokyo as APAC HQ?
Singapore wins on connectivity to Southeast Asia, India and Australia — submarine cable density (Apricot, IAX, BIFROST, etc.) makes it the natural pan-APAC gateway. Tokyo wins on raw capacity, fewer regulatory constraints, and access to the Japanese domestic market. Singapore is typically chosen for regional headquarters and pan-APAC distribution; Tokyo for North Asia or Japan-specific workloads.
Is Singapore good for AI / GPU workloads?
Possible but expensive. Power constraints and the 1.25 PUE mandate push DC-CFA2 builds toward liquid cooling and high-efficiency designs that suit AI density. However, deployment timelines are slower than alternatives like Johor (Malaysia), which has emerged as the lower-cost AI corridor for Singapore-headquartered customers — sub-millisecond latency from JB to SG core.
How do I get a Singapore colocation quote?
Take the free 2-minute assessment to specify cabinet count, power density, redundancy needs and timeline. Given Singapore's tight supply, we'll surface availability across approved CFA operators plus cross-border options in Johor (Malaysia) where appropriate — particularly for tenants where deployment speed or cost matters more than physical Singapore residency.
