Physical security standards vary more between facilities than most buyers expect, and the gap between “has cameras” and a genuinely layered, audited security programme is larger than it looks on a spec sheet.
Ask ten infrastructure leaders how they choose a data center and you will get ten different answers. Yet beneath the variety, the same handful of questions tend to decide the outcome.
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.
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.
The most expensive mistake is optimising for the number everyone sees — the monthly rack rate — while ignoring the numbers nobody asks about until the invoice arrives: cross-connects, remote hands, power overage, and renewal escalators.
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.
Good facilities make the boring things boring: predictable billing, clear escalation paths, and remote-hands requests that get done on the timeline promised, not the timeline hoped for.
A practical way to evaluate
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.
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.
A short checklist before you sign
- Clarify remote-hands response times and what is included versus billed separately
- Request recent incident reports, not just a summary uptime percentage
- Ask for real uptime history, not just the design tier
- Map the network ecosystem: carriers, internet exchanges, and cloud on-ramps
- Ask what happens operationally when a single system fails, not just what the tier rating implies
The bottom line
Markets like this reward those who prepare. Do the early thinking well, and the rest of the process tends to take care of itself.
