Water usage is the metric that gets far less attention than PUE, yet it matters enormously in water-stressed regions where a facility’s cooling design has real community impact.
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.
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.
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.
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.
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.
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.
A short checklist before you sign
- Ask for real uptime history, not just the design tier
- Leave headroom for growth, including higher-density racks down the line
- Read the exit and renewal terms as carefully as the price
- Clarify remote-hands response times and what is included versus billed separately
- Ask what happens operationally when a single system fails, not just what the tier rating implies
The bottom line
None of this is complicated, but it does reward diligence. The organisations that treat infrastructure procurement as a discipline rather than a purchase consistently end up with better facilities, better terms, and fewer surprises.
