<p>Changes the state of a file transfer protocol-enabled server from <code>ONLINE</code> to <code>OFFLINE</code>. An <code>OFFLINE</code> server cannot accept and process file transfer jobs. Information tied to your server, such as server and user properties, are not affected by stopping your server.</p> <note> <p>Stopping the server will not reduce or impact your file transfer protocol endpoint billing; you must delete the server to stop being billed.</p> </note> <p>The state of <code>STOPPING</code> indicates that the server is in an intermediate state, either not fully able to respond, or not fully offline. The values of <code>STOP_FAILED</code> can indicate an error condition.</p> <p>No response is returned from this call.</p>
