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

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.

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.

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.

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.

A short checklist before you sign

  • 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
  • Write down your power, space, and connectivity needs before you talk to anyone
  • 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.
