"99% of your users will have no clue what is meant by "This site is hosted by Heroku"" Couldn't agree more. Further I wouldn't want anyone to know where the site is hosted anyway. We have some customers on a VPS at Media Temple and use custom dns so they don't see MT's dns servers (which of course they could find out if they want to check the IP obviously). They don't need to know that info. As far as they are concerned we are the vendor. The message could simply say "We are having technical difficulties and we're working to get the service restored as quickly as possible".
