MTTR (Mean Time to Restore)

The average time it takes to recover a system or service after a failure.

Mean Time to Restore (MTTR) is one of the four DORA metrics and measures the average time it takes for a team to recover a system or service after a failure or incident. MTTR is calculated by dividing the total downtime by the number of incidents in a given period. A lower MTTR indicates a more resilient engineering team. Elite performing teams (per DORA research) achieve MTTR of less than one hour.
