How Often Should You Actually Test Disaster Recovery? — Updated for 2026 (20) — Updated for 2026 (3)

July 14, 2026 · By Data Hall Insights Team

Disaster recovery plans that have never been tested are, in practice, untested assumptions — and the gap between assumption and reality tends to surface at the worst possible time.

Behind every application your customers touch sits a physical building full of power, cooling, and fibre. The choices made about that building quietly shape performance, cost, and risk.

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.

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.

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.

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.

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.

The market has split in two. Standard enterprise workloads still run comfortably at three to five kilowatts a rack, while accelerated-compute deployments are pushing twenty, fifty, even a hundred kilowatts. Those two worlds are priced and provisioned very differently, and conflating them is a common and expensive mistake.

A short checklist before you sign

  • Total the full cost of ownership, including the fees that hide in the small print
  • Write down your power, space, and connectivity needs before you talk to anyone
  • Confirm the certifications your industry and customers actually require
  • Clarify remote-hands response times and what is included versus billed separately
  • Ask for real uptime history, not just the design tier

The bottom line

Markets like this reward those who prepare. Do the early thinking well, and the rest of the process tends to take care of itself.
