Before update your main app, you need bind the scheduled downtime app to your main app’s domain. For example, is your main app domain is, then you need bind scheculed downtime app into this domain before you update the main app.

Update AppFog App

Once your scheduled downtime page app is bind to same domain as your main app, you can start to update main app. During the main app’s downtime, all visitors will serve by your custom scheduled downtime page app without showing AppFog’s default error page thus increase your site engagement. You can futher develop the app to let user to enter email address to notify them after update is completed.
