Most colocation migrations fail on sequencing, not technology — moving the wrong workload first is a far more common cause of downtime than any hardware issue.
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.
Why it matters now
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.
Power has overtaken floor space as the binding constraint in most primary markets. Vacancy rates have fallen to record lows, and the practical effect is that capacity — particularly high-density capacity — increasingly needs to be reserved well ahead of when you actually need it.
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
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.
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.
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.
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
- Write down your power, space, and connectivity needs before you talk to anyone
- Clarify remote-hands response times and what is included versus billed separately
- Request recent incident reports, not just a summary uptime percentage
- Read the exit and renewal terms as carefully as the price
- Ask what happens operationally when a single system fails, not just what the tier rating implies
The bottom line
There is no shortcut that replaces doing the homework, but there is a real payoff for doing it well: fewer surprises, better terms, and a partner that fits for the long run.
