Once isolated, an instance cannot be used or accessed; however, it is not terminated or deleted. You can recover it in the console. After isolation, resource capacity will not be released, and the most basic data replicas will be retained. After the isolation period elapses, the instance will be completely terminated.
After an instance is returned, once its status changes to "isolated", no fees related to it will be incurred.
- After an instance is isolated, its IP will be released, and you may not get back the original IP after the instance is recovered.
- After an instance is isolated, you cannot upgrade it, modify its parameters, create or modify an account for it, roll it back, add sets to it, or rename it.
Instance recovery is to recover an isolated instance to its normal running status. The recovery may take several minutes to complete. In addition, the recovered instance may have a new IP rather than the original IP before isolation.
If you do not need an instance any longer, you can return it, and it will be isolated. An isolated instance will be completely terminated after expiration.
