server farm question

I'm not aware of any way to set the config to do exactly as you're
requesting.

However, if you write a wrapper script to do the necessary checks and
returns (0-5 servers failed, return 0; 6-15 servers failed, return 1; 16-30
servers failed, return 2), you should be good to go.  You could have one
contactgroup for the individual hosts, and another contactgroup for the
"everything has failed" service.
