AI and accelerated-compute workloads have rewritten the assumptions colocation buyers used to rely on, particularly around power density, which now regularly exceeds what older facilities were designed to deliver.
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.
Where buyers get it wrong
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.
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.
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.
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.
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.
A short checklist before you sign
- Request recent incident reports, not just a summary uptime percentage
- Leave headroom for growth, including higher-density racks down the line
- Map the network ecosystem: carriers, internet exchanges, and cloud on-ramps
- Write down your power, space, and connectivity needs before you talk to anyone
- Ask what happens operationally when a single system fails, not just what the tier rating implies
The bottom line
The good news is that you do not have to navigate it alone. With the right data and the right guidance, what feels like a daunting decision becomes a structured, confident one.
