Perhaps a bit trivial, but maybe this could be a poor man's solution to 
this problem:

Apache gives the possibility to customize its error behaviour,

http://httpd.apache.org/docs/mod/core.html#errordocument
http://httpd.apache.org/docs/custom-error.html

Maybe it's possible to just use that to redirect apache to an uri which 
delivers a nightly built static version of the site. Also, one can 
redirect to an cgi script which sends an email before redirecting to 
that static version. I just don't know for sure whether the "upstream 
host not responding" error of mod_proxy can be handled here.
