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.
Behind every application your customers touch sits a physical building full of power, cooling, and fibre. The choices made about that building quietly shape performance, cost, and risk.
Why it matters now
The market has split in two. Standard enterprise workloads still run comfortably at three to five kilowatts a rack, while accelerated-compute deployments are pushing twenty, fifty, even a hundred kilowatts. Those two worlds are priced and provisioned very differently, and conflating them is a common and expensive mistake.
What used to be a commodity is now a strategic asset class. When supply is tight, the question stops being simply how much it costs and becomes whether you can secure it at all, on terms that let you grow.
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.
The factors that actually move the needle
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.
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.
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.
Model the whole cost, not the monthly line. Setup fees, cross-connects, bandwidth, growth headroom, and exit terms all belong in the comparison. The cheapest rack rate is rarely the cheapest deployment.
A short checklist before you sign
- Ask for real uptime history, not just the design tier
- Map the network ecosystem: carriers, internet exchanges, and cloud on-ramps
- Clarify remote-hands response times and what is included versus billed separately
- Read the exit and renewal terms as carefully as the price
- Confirm the certifications your industry and customers actually require
The bottom line
None of this is complicated, but it does reward diligence. The organisations that treat infrastructure procurement as a discipline rather than a purchase consistently end up with better facilities, better terms, and fewer surprises.
