DayOne Data Centers designs and operates next-generation digital infrastructure, providing colocation and customized data center solutions for hyperscalers and large enterprises. Its rapid modular deployment uses prefabricated components and the SIJORI data corridor to deliver low-latency, scalable capacity, such as a Johor greenfield project completed in about 8.5 months. The facilities use high-efficiency liquid cooling and intelligent infrastructure management, with renewable-ready designs and low-carbon construction, including solid oxide fuel cells in Singapore. With roughly 480MW in service or under construction and 590MW planned across Asia-Pacific and Europe, DayOne aims to support high-performance computing, cloud, and AI workloads while expanding its regional footprint with strong funding from large investors.

DayOne has secured a $237 million syndicated term loan to finance its flagship hyperscale data centre in Hong Kong. The facility was arranged by a consortium of international and regional financial institutions. The funds will be used to construct and commission a next-generation data centre campus designed for high-density artificial intelligence workloads, cloud interconnects, and enterprise financial computing. The facility will feature advanced liquid cooling architecture, direct fibre routes to major subsea cable landing stations, and a target power usage effectiveness below 1.25. The financing comes as DayOne prepares for an initial public offering on US equity exchanges. The structured debt enables the pan-Asian digital infrastructure operator to accelerate construction whilst optimising its weighted average cost of capital ahead of the planned listing.
Singapore's DayOne Data secures $415M green loan for hydrogen-powered data center. DayOne Data Centers, a Singapore-headquartered digital infrastructure company, has secured a four-year, S$530 million ($415 million) green loan from the Singapore banks DBS, OCBC and UOB to fund its first data center in the country. In a statement on Tuesday, lender DBS said the facility can become Singapore's first to generate power on site using hydrogen fuel cells. The 20-MW facility is in the western part of Singapore. It broke ground in July 2025 and is expected to begin operating in the first quarter of 2027. The loan was structured under the Green Loan Principles, an international framework for environmentally focused lending. DBS, OCBC, and UOB acted as joint mandated lead arrangers, bookrunners and green-loan coordinators, with DBS also serving as facility and security agent. The data center can include on-site solid oxide fuel cell power generation as a proof-of-concept for hydrogen-based energy, which DayOne and the banks said would be a first for Singapore. It will also use vertical building-integrated solar panels and a combination of air and liquid cooling. Han Kwee Juan, group head of institutional banking at DBS, said demand for digital infrastructure was rising as AI and cloud computing increased energy consumption. The financing can support more energy-efficient facilities, the executive added. Elaine Lam, head of global corporate banking at OCBC, said innovative energy solutions would play a growing role in supporting digital infrastructure sustainably. Founded in 2022, DayOne operates data centres across Asia and Europe, with a presence in Singapore, Malaysia, Indonesia, Thailand, Japan, Hong Kong, Finland and Spain.

August 20, 2026 at 4:56 PM GMT+8 Singapore-headquartered data center platform DayOne has today purchased 78.80 acres of land in Sepang for the price of RM617.8 million (US$ 152.8 million) from property developer, Mah Sing Group Berhad, to develop a data center. The transaction was sealed through WG Malaysia X Sdn Bhd (a wholly-owned subsidiary of Dayone Data Hub II Sdn Bhd, itself a subsidiary of DayOne) and Southville City Sdn Bhd, a wholly-owned subsidiary of Mah Sing. The purchase price was paid in cash with the completion date expected in 2H2027. The deal involves three parcels of freehold vacant land which forms part of the 428.84-acre Southville City township which Mah Sing plans to unlock to support its future growth including itself pivoting into the digital infrastructure sector as a second growth engine. "The disposal is intended to support Mah Sing's broader digital infrastructure strategy and the continued development of Mah Sing DC Hub @ Southville City; and provide the Group with greater flexibility to progressively participate further up the digital infrastructure value chain, including enabling infrastructure, core-and-shell facilities and ownership of income-generating digital infrastructure assets alongside experienced operators," the firm said in a Bursa exchange announcement. Property development remains the group's core activity and primary source of income. Completion of the sale is subject to several conditions including the issuance of a new title to the land, approvals from the Data Centre Task Force and PLANMalaysia, among others.
Malaysian property developer Mah Sing sells land in Selangor to DayOne. DayOne expanding landholdings in Malaysia August 20, 2026 Malaysian property developer Mah Sing is selling land in Selangor to data center developer DayOne. In a stock exchange announcement, the company announced this week that its wholly owned subsidiary, Southville City Sdn Bhd (SVCSB), sold land in Daerah Sepang, a district south of Kuala Lumpur. SVCSB this week entered into a conditional Sale and Purchase Agreement (SPA) with WG Malaysia X Sdn Bhd for the sale of 78.80 acres of freehold land located in Southville City township, Mukim Dengkil. The deal was for a total cash consideration of RM617.8 million ($152.8m). The land is currently vacant, and the buyer intends to develop it into a data center. The deal is set to close in the second half of 2027. Selangor, a western state on Peninsular Malaysia, contains the Klang Valley, which is Malaysia's second-largest data center market by capacity and its colocation hub. WG Malaysia X Sdn Bhd is a subsidiary of DayOne Data Hub II Sdn Bhd. Founded as a plastics manufacturer in the 1960s, Mah Sing ventured into property development in 1994. The company has 58 projects across more than 5,300 acres, spanning residential, township, office, retail, and industrial developments. Bridge DC was previously set to develop a data center on Mah Sing-owned land in Southville City, but backed out. APAC-focused DayOne was spun out of Chinese data center firm GDS back in 2025. The company's portfolio currently comprises more than 500MW of data center capacity in service and under construction, and more than 500MW held for future development across sites in Hong Kong, Singapore, Malaysia (Johor), Indonesia (Batam), and Japan (Tokyo). The company recently broke ground on a site in Thailand and another in Singapore. In August, it made its first foray into markets beyond Asia, announcing a campus in Lahti, Finland. DayOne acquired 65 acres of land in Johor from Malaysian property group Paragon Globe earlier this year. Get a roundup of the latest regional news across Asia fortnightly.

DayOne has secured a four-year SGD530 million ($414.7 million) green loan from DBS, OCBC and UOB to develop its first data centre in Singapore. The facility, which broke ground in July 2025, is expected to be operational by Q1 2027 and will be Singapore's first data centre with on-site Solid Oxide Fuel Cell power generation as part of a hydrogen-based energy proof-of-concept. The 20-megawatt data centre, located in western Singapore, will feature vertical building-integrated photovoltaics and hybrid air and liquid cooling technologies. It achieved BCA Green Mark Platinum certification in December 2025. The loan is structured according to Green Loan Principles, with the three banks acting as joint mandated lead arrangers, bookrunners and green loan coordinators.
