DayOne SIJORI AI Data Center Hub in Malaysia
Status: Construction / Expansion Phase | Location: Cross-border SIJORI Corridor, batam
Project Overview
The DayOne SIJORI Hub is a multi-country "super-campus" strategy designed to bypass the land and power constraints of Singapore by creating a seamless, low-latency network across the SIJORI (Singapore-Johor-Riau) growth triangle. As of January 2026, DayOne has secured approximately 1GW of customer commitments, largely driven by the surge in sovereign AI and hyperscale cloud demand in Southeast Asia.
The project is technically distinguished by its "AI-first" engineering. Every facility in the SIJORI hub is being fitted with direct-to-chip liquid cooling (DLC) and modular power skids to support high-density GPU clusters. In Batam (Indonesia), DayOne is leveraging the region’s emerging renewable energy infrastructure to provide a "Green Corridor" for Singapore-based firms that need to meet strict ESG targets. This project isn't just a building; it is a cross-border digital utility that allows a company to host its primary compute in Singapore while offloading heavy AI training workloads to higher-capacity, lower-cost sites in Johor and Batam, all linked by DayOne’s proprietary dark fiber backbone.
