idea for heroku : allow customers to host a "my app is down page for blah blah reason" where they host their status page (rackspace I guess?). Who think this would be useful? My users see a blank page right now when they go to ZeTrip, I'd rather show them a static page saying : "our site is down due to amazon lack of redundancy."

Cloudflare lets you do this afaik. I'm not sure I'd trust a service to show a proper 'this site is temporarily down' page when something very bad has happened.
