Reboot Instances operation


The Reboot Instances operation enables you to request a reboot of one or more instances.

The Reboot Instances operation is asynchronous and this operation queues a request in Amazon EC2 to reboot the specified instance or instances.

Note

The Reboot Instances operation succeeds only if the instances are valid and if the instances belong to you. Amazon EC2 ignores requests to reboot terminated instances.
