The ledger is fully accessible without any performance impact while the key change is being processed. The amount of time it takes to update a key varies depending on the ledger size.</p> </li> <li> <p> <code>KMS_KEY_INACCESSIBLE</code>: The specified customer managed KMS key is not accessible, and the ledger is impaired. Either the key was disabled or deleted, or the grants on the key were revoked. When a ledger is impaired, it is not accessible and does not accept any read or write requests.</p> <p>An impaired ledger automatically returns to an active state after you restore the grants on the key, or re-enable the key that was disabled. However, deleting a customer managed KMS key is irreversible. After a key is deleted, you can no longer access the ledgers that are protected with that key, and the data becomes unrecoverable permanently.</p> </li> </ul>"
