Due diligence on a colocation provider is worth treating like due diligence on any critical vendor: verify what is claimed, do not just read what is published.
There is a quiet shift happening in how organisations think about where their infrastructure lives. What was once a purely technical decision now sits squarely on the boardroom agenda, and for good reason.
What good looks like in practice
The best partnerships look less like a vendor relationship and more like a shared roadmap — regular capacity reviews, early visibility into expansion options, and a provider that flags risk before it becomes your problem.
The strongest operators are transparent by default — uptime history, incident reports, and maintenance schedules are available without a special request. That openness is itself a signal worth weighing.
A practical way to evaluate
Then shortlist on objective data and validate with your own eyes. Marketplace intelligence is excellent for narrowing the field quickly, but a site visit and a couple of reference calls will tell you things no datasheet can.
Start with requirements, not providers. Pin down your power per rack, total committed capacity, connectivity needs, and the compliance regimes you answer to. That single page of clarity will shape every conversation that follows.
The factors that actually move the needle
Headline pricing is the least reliable basis for comparison. Two facilities quoting similar rates can differ enormously once you account for power redundancy, cross-connect fees, remote-hands rates, and the small print around escalations and renewals.
Connectivity richness is frequently underweighted. A carrier-neutral facility with a dense ecosystem of networks and direct cloud on-ramps can save more over a contract term than a modest difference in the rack rate ever will.
Where buyers get it wrong
Treating tier level as a proxy for reliability is a common shortcut that backfires. Design tier describes redundancy on paper; actual uptime depends on maintenance discipline, staffing, and how the facility has behaved under real incidents.
Underestimating growth is more common than overestimating it. Teams that lock in exactly what they need today frequently find themselves negotiating from a weaker position twelve months later, once the facility has less spare capacity to offer.
A short checklist before you sign
- Clarify remote-hands response times and what is included versus billed separately
- Ask what happens operationally when a single system fails, not just what the tier rating implies
- Request recent incident reports, not just a summary uptime percentage
- Write down your power, space, and connectivity needs before you talk to anyone
- Leave headroom for growth, including higher-density racks down the line
The bottom line
The teams that get this right are rarely the ones with the most resources — they are the ones who asked better questions earlier in the process.
