Making site offline

i am not sure if this would help or no but give it a try.

in your default application create a custom hook.

create either a "pre_controller" or a "post_controller_constructor"


this hook would go and check if an update is in progress. if so then kill the request and redirect to a "server is under update" page.

just remember that your cron job should reset whatever it is that tells the hook that update is in progress. it can be a temp file or a database record.
