Providing a server polling component for remote cryptographic key erasure resilient to network outage. A set of keys received from a server are stored on data storage. The data storage sends a status request to the server. If a key enabled status is received, the data storage continues normal operations. If a key disabled status is received, a key failure action is performed. The key failure action includes deleting one or more of the keys in the set of keys or shutting down one or more storage devices of the data storage. If no response is received from the server, the data storage iteratively resends the status request at retry time intervals until a response is received from the server or until a time out period expires. On expiration of the time out period, the key failure action is performed.
