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.
It is easy to underestimate how much rides on a single colocation decision until you are twelve months into a contract that no longer fits. Getting the early thinking right pays off for years.
Planning for what comes next
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.
Geography is strategy. Where your data physically sits affects latency, sovereignty, and resilience. Spreading critical workloads across regions is no longer just for the largest enterprises.
Why it matters now
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 used to be a commodity is now a strategic asset class. When supply is tight, the question stops being simply how much it costs and becomes whether you can secure it at all, on terms that let you grow.
Where buyers get it wrong
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.
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 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 short checklist before you sign
- Request recent incident reports, not just a summary uptime percentage
- 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
- Map the network ecosystem: carriers, internet exchanges, and cloud on-ramps
- 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.
