7 Best Colocation Data Centres in Singapore (2026)

Colocation means renting space, power and cooling in someone else's data centre while keeping ownership of your own servers. Singapore has a dense cluster of operators, and they serve very different customers: some sell a single unit of rack space to a small business, others lease whole suites to cloud providers. This list covers seven operators across that range, drawn from each company's own website. Descriptions are attributed to those pages rather than independently audited, so treat tier, uptime and certification wording as the operator's claim. Read the how-to-choose notes first, then ask every shortlisted provider for current terms, a site visit and its written service levels.

Exabytes is better known for domains and web hosting, but its site also lists a server colocation service in Singapore. The colocation page describes plans ranging from a single unit of rack space up to a full 42U rack, with quarter and half rack steps in between, and says remote hands staff can reboot, check cables or swap hardware on a customer's behalf. It describes the facility as Uptime Institute Tier 3 certified, connected to the Singapore Internet Exchange and covered by a network uptime SLA; those are the company's statements, so ask to see the paperwork. The page also mentions a Johor Bahru facility. It suits small businesses wanting hosting and rack space from one vendor.

QUAPE, a Singapore hosting company, publishes a colocation page aimed at teams that own their hardware but do not want to run a server room. Its listed options run from shared rack space for a single unit up to a dedicated private 42U rack, with power allowances and bandwidth stated per plan. The page says its facilities are TIA-942 data centres backed by a written 99.9 percent uptime SLA, and that remote hands tasks such as reboots, cable checks and part swaps can be arranged, with scope to be confirmed. It also states plainly that colocation is infrastructure only, so monitoring, backups and application support need separate agreements. A candid, small-scale option for single servers.

DataCenter.SG presents itself as a colocation specialist, and its colocation page lists quarter, half and full rack formats rather than a hyperscale-only model. The site describes a carrier-neutral facility with access to many network providers, direct links to the major public clouds and remote hands support included with plans. It also lists Tier III, ISO 27001, SOC 2 Type II and PCI DSS wording, along with redundant power and cooling, biometric access control and early smoke detection. These are the operator's own claims and the page does not show audit reports, so request certificates before relying on them. The site places the facility in the Ubi industrial area. A reasonable first call for businesses wanting rack-level colocation with a security and compliance emphasis.

Global Switch is an international data centre operator, and its Singapore page describes two sites: Tai Seng and Woodlands. It says Tai Seng is among the most connected facilities in the Asia-Pacific region, serving cloud, enterprise and network providers, and that Woodlands offers scalable space and flexible power for workloads from enterprise to very high density compute. The company's wider materials describe private suites, cages and racks, plus meet-me rooms for carriers, and a technical specification document for the Tai Seng site. This is a larger-scale, connectivity-focused operator, so smaller firms should confirm minimum commitments before enquiring. Its site did not print a specific tier rating or certification on the page reviewed, so ask.

ST Telemedia Global Data Centres is headquartered in Singapore and describes itself as a colocation provider with an international footprint. Its Singapore page lists six facilities spread across the Defu industrial estate, the one-north business park, Tai Seng and Loyang, and groups its offer under colocation, connectivity and support services. Press material on its site also mentions an expansion of its Defu campus and an internet exchange point of presence at its Tai Seng location. The operator is oriented toward enterprise and cloud customers needing sizeable capacity, so expect a sales-led process rather than self-service plans. Ask which specific building would host you and what certifications that building holds, since the page reviewed did not itemise them.

Keppel Data Centres is the data centre arm of the Keppel group, and its press releases describe carrier-neutral, purpose-built colocation facilities in Singapore. Releases place several in Tampines and describe a newer campus where the latest building is characterised as Tier 3 equivalent, fully leased to cloud, internet and telecommunications clients, and recognised with a BCA Green Mark Platinum award. That wording is Keppel's own and relates to specific buildings, not every site. The company positions its offer around wholesale, build-to-suit and hyperscale capacity, so it is most relevant to large organisations rather than a single-server buyer. A smaller business should ask whether suitable space is available at all before investing time in a proposal.

NeutraDC describes itself as a regional operator of carrier-neutral, hyperscale-ready data centres across Southeast Asia, and its Singapore page offers colocation with on-site support for enterprise-scale needs. The site emphasises AI-ready infrastructure for GPU clusters and high-bandwidth networking, so it reads as aimed at demanding compute workloads rather than a lone web server. It says it is backed by industry leaders and certified for excellence, but the page reviewed did not name a specific tier rating or certificate, so ask for the exact standards and the building in question. The site lists a HarbourFront office for the Singapore business. Consider it if you expect to grow into high-density capacity or want a regional footprint beyond Singapore.
