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.

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.

A practical way to evaluate

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.

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.

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.

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

  • Map the network ecosystem: carriers, internet exchanges, and cloud on-ramps
  • Write down your power, space, and connectivity needs before you talk to anyone
  • Total the full cost of ownership, including the fees that hide in the small print
  • Clarify remote-hands response times and what is included versus billed separately
  • Leave headroom for growth, including higher-density racks down the line

The bottom line

The teams that get this right are rarely the ones with the most resources — they are the ones who asked better questions earlier in the process.
