Oracle Cloud Infrastructure Customer,
Oracle Cloud Infrastructure (OCI) has reclaimed idle Always Free compute resources from Always Free customers by stopping the compute instance(s). Reclaiming idle resources allows OCI to efficiently provide services to Always Free customers. Your account had one or more idle compute instances that have been stopped. You can restart your compute instance as long as the associated compute shape is available in your region. In the future, you can keep idle compute instances from being stopped by converting your account to Pay As You Go (PAYG). With PAYG, you will not be charged as long as your usage for all OCI resources remains within the Always Free limits.
