If the reconnection is done before the session expires, the ephemeral is never deleted.
If the session expires either due to time when disconnected or because the ZK servers are all taken down, then the ephemeral is deleted when the server decides the session has expired and the client is notified of the session expiration as soon as possible. Ephemerals are never brought back after the session expires. Note that taking down one ZK server of many will just cause a very short disconnect. If even one ZK server stays up, the session and the ephemeral can survive although a quorum will have to be re-established soon to preserve the session.
