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

July 23, 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.

There is a quiet shift happening in how organisations think about where their infrastructure lives. What was once a purely technical decision now sits squarely on the boardroom agenda, and for good reason.

Planning for what comes next

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.

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.

A practical way to evaluate

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.

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.

Where buyers get it wrong

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 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.

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.

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.

A short checklist before you sign

  • Clarify remote-hands response times and what is included versus billed separately
  • Ask for real uptime history, not just the design tier
  • Request recent incident reports, not just a summary uptime percentage
  • Map the network ecosystem: carriers, internet exchanges, and cloud on-ramps
  • Ask what happens operationally when a single system fails, not just what the tier rating implies

The bottom line

The good news is that you do not have to navigate it alone. With the right data and the right guidance, what feels like a daunting decision becomes a structured, confident one.
