As Arthur says, losing power won't give you a closing event. You also have to decide what to do if the internet connection is lost for whatever reason (how long is 'lost' as opposed to 'misplaced'? You may just have gone into a train tunnel which doesn't have an internet connection (not all of them do where I am)). If it's important, then pinging the server at regular intervals might be your best bet.
