I guess the idea of putting comic sans MS as a way to force companies into putting relevant customised status error messages for users has failed.

EDIT see here: https://news.ycombinator.com/item?id=9240906

For 500 a ticketing or a contact info to report the problem For a 404 whatever can help the user finds it way For congestion status a link to a status page? For stuff 40? that requires payment a link with a link for legitimately acquiring it ... The webmasters email in case there is something to report could be nice too ...

It really is business meaningful to customize them, I fully support shaming irresponsible webmasters that keep default status pages with comic sans MS.
