*Issue:* The regional failover process during the incident was slow because the procedure was not recently practiced or well-documented.
*Corrective Action:* Schedule and conduct a full disaster recovery (DR) drill each quarter. This exercise will include failing over production traffic, verifying full system functionality in the secondary region, and then failing back. The entire procedure must be updated in the official runbook.
*Result:* Regular DR drills will reduce the Mean Time to Recovery (MTTR) during a real outage and ensure the failover process remains effective.
