How to Choose a Colocation Provider: 8 Questions to Ask

Choosing a colocation provider is a multi-year commitment — your hardware, your uptime, and often your compliance posture depend on it. Here are the questions worth asking before you sign anything.

---

1. Where is the facility, and who can access it?

Location affects latency to your users and how quickly your team (or the provider's remote hands) can respond to a physical issue. Ask about physical access controls too — biometric access, visitor logs, and 24/7 monitoring should be standard, not optional extras.

2. What's the actual redundancy — and is it certified?

Ask specifically about power and cooling redundancy (N+1, 2N, etc.) and whether any Tier rating is a formal Uptime Institute certification or just marketing language. See our guide to data center tiers for what each level actually guarantees.

3. What's their track record on downtime?

Ask when they last had an outage, what caused it, and how long it took to resolve. A provider who answers this honestly and specifically is a better sign than one who claims flawless history.

4. What connectivity options do they offer?

Multiple carrier-neutral ISP connections reduce your risk of a single point of failure. Ask whether you can bring your own carrier if needed, and what bandwidth is included versus billed separately.

5. What compliance certifications do they hold?

If you handle regulated data, confirm relevant certifications (ISO 27001, SOC 2, PCI-DSS, or industry-specific requirements) rather than taking "we're compliant" at face value — ask for the actual certificates.

6. Is pricing genuinely transparent?

Rack space is rarely the only cost. Ask explicitly about power overage charges, bandwidth billing, remote-hands rates, and setup fees before you compare quotes — see our colocation pricing breakdown for the full list of line items to check.

7. How easily can you scale?

Ask whether they can accommodate growth from a few rack units to a half or full rack without relocating you, and how much notice they need for capacity expansion.

8. What support do they actually provide?

Confirm whether remote-hands support is included or billed per incident, what their guaranteed response time is, and whether support is available 24/7 or business hours only.

Final Thoughts

The right colocation partner should be able to answer all eight of these clearly and specifically — vague answers on redundancy, pricing, or support history are a warning sign. At Quantarock, we're upfront about our infrastructure, certifications, and pricing because we'd rather earn a long-term relationship than a quick sign-up.
