how do i make a mastodon 500 page show a maintenance message vs. a generic error message? i wanna show when it's down because of an upgrade

@squirrel I guess the uh. "easy" way? is to have a different 500 page you copy in right before you go down for maintenance and then copy the normal one back in when you're back up

@InspectorCaracal yeah haha that's what i thought

@squirrel actually I think I might know how to do that but I have to get on a computer to check
