Colocation — putting your own servers in a data centre rather than hosting them in your office or on public cloud — still has a strong business case in 2026. For businesses running workloads that need dedicated hardware, sovereign data residency, or control over custom configurations, colocation offers enterprise-grade infrastructure without the cost of building your own data centre.
But not every colocation provider is equal, and choosing wrong leaves you with latency issues, poor support, unexpected bills, or — worst case — a compliance problem when an auditor asks where your data lives. Here’s what to evaluate before signing a contract.
1. Data Centre Tier and Physical Redundancy
Data centres are rated by the Uptime Institute on a Tier I–IV scale. Tier III is the practical minimum for business-critical workloads — it provides concurrent maintainability (you can do maintenance without bringing the site down). Tier IV adds fault tolerance, meaning the site tolerates a single failure without any service impact.
Ask for evidence: certified Tier rating, documented uptime SLA (aim for 99.99% or better), redundant power feeds, generator backup with fuel contracts, and N+1 or 2N cooling. For production workloads, anything less than Tier III is risk you shouldn’t accept.
2. Location and Australian Data Residency
For Australian businesses, hosting your data in Australia matters more than ever. The Privacy Act amendments, APRA CPS 234, and industry-specific regulators (health, financial services, legal) all have either explicit or implied preferences for Australian data residency. Cyber insurance policies increasingly ask about it too.
Brisbane, Sydney, and Melbourne have multiple Tier III+ data centres. For businesses based in Brisbane, a local data centre also means lower latency, simpler physical access for hands-on work, and easier response when you need someone to physically swap a failed disk.
3. Bandwidth, Carriers, and Cross-Connects
A data centre that only offers one or two carriers locks you in. Good colocation facilities are “carrier-neutral” — you can choose from multiple internet providers and switch without moving hardware. Look for:
- Multiple tier-1 carriers on-site
- Direct cross-connects to AWS, Azure, and Google Cloud (for hybrid architectures)
- Peering with major Australian ISPs
- Burstable or flexible bandwidth options (pay for what you use)
- Diverse fibre paths (so a single cable cut doesn’t take you down)
4. Physical Security and Compliance Certifications
Your hardware sits in someone else’s building. Physical security matters. Evaluate:
- 24/7 manned security with CCTV coverage
- Multi-factor access control (biometric plus card or PIN)
- Visitor logging with government-ID verification
- Locked cabinets or cages with audit trails
- Industry certifications: ISO 27001, SOC 2 Type II, IRAP (for government-related workloads)
- Sector-specific compliance if relevant: PCI DSS, HIPAA-equivalent, etc.
These aren’t just boxes to tick — they’re what you’ll point to when auditors or insurers ask about your data protection controls.
5. Remote Hands and Support
Eventually you’ll need physical work done — a failed disk, a stuck boot, a cable swap — and you won’t always have someone available to drive to the data centre at 2am. “Remote hands” is the data centre’s ability to do physical work on your hardware on your behalf.
Ask about:
- Response times for remote hands requests
- Cost structure (included hours vs per-incident charges)
- Technical competence of on-site staff (a trained engineer vs an overnight security guard)
- Documentation requirements (how they confirm what work to do)
- 24/7 availability or business-hours only
For business-critical workloads, skimping on remote hands is how short outages become long outages.
Colocation vs Cloud in 2026
Many businesses assume the choice is binary: “everything to cloud” or “stay on-premise forever.” In reality, most SMBs end up with a hybrid: Microsoft 365 for productivity and collaboration, cloud for scalable or dev/test workloads, and colocation for legacy or specialised applications that are expensive or disruptive to migrate.
Colocation makes particular sense when:
- You have significant investment in existing hardware that’s still useful
- Workloads have predictable, steady resource usage (cloud’s auto-scale value is lost)
- Compliance or data sovereignty requires dedicated hardware
- Custom hardware (specialised NICs, GPUs, HSMs) is required
- You need low-latency connections to other tenants or on-ramps to cloud
What It Costs — and What Hidden Costs to Watch
Colocation pricing typically includes rack space, power allocation, and basic bandwidth. Watch for:
- Power overage charges — power is often metered, and exceeding your allocation costs more
- Remote hands billing — per-incident charges that add up quickly
- Bandwidth overage — especially for high-traffic applications
- Cross-connect fees — monthly charges for each fibre patch to another tenant or carrier
- Long contract terms — 3-year commitments are common, but pricier options without lock-in exist
