Cross-Border AI Infrastructure: DayOne SIJORI Data Center Hub
Status: Construction / Expansion Phase | Location: Cross-border SIJORI Corridor
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 1 GW 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.
