Rollback Procedure overview

Emergency workflow activated when a deployment introduces regressions severe enough to require reverting to the previous stable version. The on-call SRE or engineer identifies the bad deployment via dashboards or alerts, confirms the rollback decision with the incident commander, and executes the rollback through the deployment pipeline or manually via CLI tooling. Database migrations may require special handling to ensure backward compatibility. After rollback, services are verified healthy, affected users are notified, and the deployment is flagged for post-mortem investigation. Speed and decisiveness are the primary objectives.
