The incident was triggered by an AWS availability issue affecting underlying compute and storage in a single availability zone. That event left the search cluster without a healthy master node, which caused search requests to time out or fail. During recovery, the master node could not restart because its persistent volume was still marked in use on the impacted instance, delaying failover until the volume attachment problem was resolved and healthy search capacity was restored. This is affecting only the AWS hosted instances. Please refer AWS status page: https://health.aws.amazon.com/health/status?path=open-issues
