Received degradation notice. Restarted instance during outage window. AWS Rebooted it anyway

Question

We receive hardware degradation notices periodically, and always try to restart the host ourselves to migrate it before AWS doe it autonomously. We did a restart on one last weekend, and today, AWS rebooted the host anyway. The notice states

* What will happen when I stop and start the instance?
You can stop and start the instance at any time before the scheduled start time of the scheduled reboot event. This will migrate the instance to a new host and the instance will not have to undergo the scheduled maintenance.

Why then, if we had already stopped and started the instance, would it perform the maintenance anyway?

Accepted Answer

Sorry to hear that. Did you check to confirm the description of the scheduled events changed to **[Completed]** after you manually reboot the instance before the scheduled reboot? It could be possible that the manual reboot didn't clear the scheduled event or another reboot is required. Here is more [detail](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/monitoring-instances-status-check_sched.html) how to react to scheduled events for instances.
