Hi Team,

We had a 3 node ES cluster and that has been hosted on AWS . We can see below error message, after the amazon network connectivity issue( see https://status.aws.amazon.com/) which is happen on today. Could you please advise how I can bring up the cluster again to good state, without any data?

You can either delete the .marvel-2015.03.16 index (and lose the corresponding data) or restore it again from a snapshot if you've done regular backups.
