Deferred maintenance is disabled for a Redshift cluster. The ""defer maintenance"" attribute of a Redshift configuration allows you to postpone maintenance of a cluster and keep your warehouses running without any interruptions during peak/critical business timespans. The maintenance can be deferred by up to 45 days. If the feature is disabled, you may experience downtime during crucial business periods.
Recommended Mitigation
Consider enabling the 'defer maintenance' feature and postpone scheduled maintenance to run during off-peak hours.
