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.
The economics of data center capacity have changed faster in the last two years than in the previous decade. Anyone evaluating their options today is working in a genuinely different market.
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.
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.
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.
The factors that actually move the needle
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.
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.
A short checklist before you sign
- Ask for real uptime history, not just the design tier
- 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
- Read the exit and renewal terms as carefully as the price
- Clarify remote-hands response times and what is included versus billed separately
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.
