When an administrator needs to perform some system maintenance operations we may need to keep users out of the system - but the system has to remain up. Eg. Large hierarchy change with data moves and security access changes. Or an upgrade where we need to do various checks before allowing the user back in to resume their work. Ideally we should be able to see who is connected and also ping an alert message to logged in users to advise them if the system is about to be made unavailable.
