Not sure exactly what you are referring to, but it is probably waiting, trying to contact the server. It must wait for a certain period of time before giving up (called a timeout). If you have a slow/poor connection, or the server is busy, it could take up to 30 seconds to get a response. If it didnt wait, you might never reach our server. If you wish to avoid this somewhat, set the screensaver to 'temporarily not connect to the internet' and it won't have this delay. Then undo this option say, once a week, when you want to upload data.
