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.
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
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.
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.
Tier classification tells you what a facility was designed to do, not how well it is run. A well-operated Tier III site routinely outperforms a poorly managed Tier IV one on the metric that matters: real-world availability.
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.
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.
A short checklist before you sign
- Ask what happens operationally when a single system fails, not just what the tier rating implies
- Confirm the certifications your industry and customers actually require
- Ask for real uptime history, not just the design tier
- Request recent incident reports, not just a summary uptime percentage
- Leave headroom for growth, including higher-density racks down the line
The bottom line
The teams that get this right are rarely the ones with the most resources — they are the ones who asked better questions earlier in the process.
