+### What happens to my deployments during a maintenance window?

+Deployments and runbook runs on Octopus Cloud are resilient. If a [maintenance window](/docs/octopus-cloud/maintenance-window) or node restart interrupts a deployment or runbook run, it continues automatically once your instance is back online, rather than failing. You don't need to manually re-run them afterwards. Other task types are not yet resilient and may be abandoned during an outage.

-One impact of an outage is that deployments and runbook runs may fail. We are actively working on [Resilient Scalable Deployments](https://roadmap.octopus.com/c/95-alpha-program-resilient-scalable-deployments-in-octopus-cloud) to allow deployments and runbook runs to resume post-outage.

 title: Rerun all canceled deployments and runbook runs after node shutdown.
 description: An example script that determine which deployments and runbook runs were canceled because of a node shutdown and resubmit them.

+**Octopus Cloud:** This script is no longer needed for deployments and runbook runs. On Octopus Cloud, these tasks are resilient — they continue automatically after a node restart or maintenance window rather than being cancelled. This script remains useful for self-hosted High Availability instances, where node restarts still cancel active tasks.

 This script demonstrates how to programmatically determine which deployments and runbook runs can be resubmitted because they were canceled because of a node shutdown.  The node could have been shutdown for normal reasons, or it could have stopped responding, or it could have been turned off.
