ICS / OT Downtime cost calculator

Frequently asked questions

• What is optimal uptime according to benchmark recommendations?

  There is no single “optimal” uptime target that applies to all OT environments. Acceptable uptime depends on industry, process criticality, safety requirements and regulatory constraints. Many industrial organizations aim for very high availability, but even small amounts of unplanned downtime can have a disproportionate operational and financial impact. This is why OT teams focus not only on preventing downtime, but also on minimizing recovery time when incidents occur.

• Why is downtime so costly for OT environments?

  Downtime in operational technology environments halts or degrades physical production, disrupts supply chains, and can lead to missed deliveries, quality losses or regulatory exposure. In many cases, lost production time cannot simply be recovered later due to batch limits, safety requirements or validation steps. Beyond direct financial impact, extended downtime can also affect customer trust and long-term operational performance.

• How accurate is the calculator?

  The calculator provides a realistic estimate based on industry benchmarks and the values you provide. While it is not a substitute for a detailed site assessment, it offers a defensible baseline to help you understand potential exposure and the impact of reducing downtime.

• Why use a 20% default recovery improvement?

  In many OT environments, recovery goes beyond restarting systems and includes OS rebuilds, configuration restoration, validation, and stabilization. Even modest improvements such as standardized backups or partial automation can reduce manual effort, errors and coordination delays. The 20% reduction is a conservative assumption reflecting partial efficiency gains, not full automation. Because recovery practices vary by site and industry, this figure should be adjusted to match your environment and expected improvements.

• Who is the Acronis downtime calculator intended for?

  This calculator is designed for organizations that rely on operational technology, including manufacturing, energy, pharmaceuticals, logistics, utilities and other critical infrastructure sectors. It is intended for operations, engineering, security and leadership teams looking to better understand and reduce the financial impact of unplanned downtime.

• Is this calculator intended for legal, financial or compliance decisions?

  The calculator provides estimates intended to help you understand potential impact and compare scenarios. The calculator is not a substitute for a detailed operational, financial or risk assessment.

• Does this calculator account for recovery and restart time?

  Yes. The calculator is designed to reflect total downtime, which may include system recovery, validation and ramp-up time until operations are stable again. This approach aligns with how downtime is experienced in real OT environments.

• What happens when the systems supporting an AI-enabled OT solution cannot be restored to a validated state?

  AI solutions can improve OT performance, but their value depends on the availability and integrity of the systems that support them. If an AI inspection station, analytics server, historian, MES node or supervisory workstation fails, production may continue physically while validation, release, reporting or coordination is disrupted. This calculator helps estimate the financial impact of that downtime, including lost production, labor and overhead costs. It also shows how faster, predictable recovery with Acronis can reduce exposure by restoring critical OT systems to known-good, validated states.
