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.
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.
Underestimating growth is more common than overestimating it. Teams that lock in exactly what they need today frequently find themselves negotiating from a weaker position twelve months later, once the facility has less spare capacity to offer.
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.
Planning for what comes next
Whatever you commit to today, leave yourself room to grow. The right partner offers a clear path from a single rack to a private suite, and from standard density to liquid-cooled high-density halls, without forcing a migration.
Term length is a lever worth pulling thoughtfully. Longer commitments unlock materially better rates and, increasingly, priority access to scarce capacity — but only commit ahead if you are confident in the trajectory.
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.
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
- Map the network ecosystem: carriers, internet exchanges, and cloud on-ramps
- Read the exit and renewal terms as carefully as the price
- Ask what happens operationally when a single system fails, not just what the tier rating implies
- Request recent incident reports, not just a summary uptime percentage
- Leave headroom for growth, including higher-density racks down the line
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.
