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.
It is easy to underestimate how much rides on a single colocation decision until you are twelve months into a contract that no longer fits. Getting the early thinking right pays off for years.
A practical way to evaluate
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.
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.
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 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.
Where buyers get it wrong
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 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.
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.
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.
A short checklist before you sign
- Ask for real uptime history, not just the design tier
- Write down your power, space, and connectivity needs before you talk to anyone
- Confirm the certifications your industry and customers actually require
- Request recent incident reports, not just a summary uptime percentage
- 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.
