Interconnection density compounds in value over time: every additional carrier and cloud on-ramp in a facility makes it more attractive to the next tenant, which is precisely why the strongest hubs keep getting stronger.
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.
The factors that actually move the needle
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.
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.
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.
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.
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.
A short checklist before you sign
- Ask for real uptime history, not just the design tier
- Total the full cost of ownership, including the fees that hide in the small print
- Ask what happens operationally when a single system fails, not just what the tier rating implies
- Leave headroom for growth, including higher-density racks down the line
- Clarify remote-hands response times and what is included versus billed separately
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.
