Reactivates a pay-as-you-go instance for which you have overdue payments


When you call this operation, take note of the following points:

  • The instance must be in the Stopped state.

  • Instances that are stopped due to overdue payments are released after 15 days, and data on the instance can no longer be recovered. To avoid this, complete any outstanding payments and reactivate the instance within 15 days. If you cannot reactivate a VPC-type instance, wait a few minutes and try again.

  • After the operation is called, the instance enters the Starting state.
  • You cannot call this operation on ECS instances that are locked for security reasons. An instance is locked for security reasons if OperationLocks in the response returned when you query information of the instance contains "LockReason": "security". For more information, see API behavior when an instance is locked for security reasons.


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
