Offline landing page(on-premise)

Hi there, What would be the best way to detect whether an app is not running anymore and supply an alternative page to the client to inform them of the problem? For example if the app is down temporarily while a new package or server is being installed, I would like to show something other than the static Mendix HTML login page. How would I achieve this?

When using a webserver, it should be possible to redirect the user to a static page which is served by the webserver.
