MTTR, or Mean Time to Recover (also Mean Time to Repair), measures the average duration between the detection of a failure and the restoration of normal service. It is one of the four key incident metrics used in site reliability engineering and IT operations.
MTTR is calculated by dividing the total downtime caused by failures by the number of failures in a given period. For example, if a service experienced 3 outages totaling 90 minutes of downtime in a month, the MTTR would be 30 minutes.
Reducing MTTR is a primary goal for operations teams. Strategies include implementing automated alerting, maintaining runbooks for common failure modes, using on-call rotations to ensure fast response, and conducting blameless postmortems to prevent recurrence. Hyperping helps reduce MTTR by detecting issues within seconds and routing alerts through escalation policies to the right responder.
