The correct answer probably depends on your definition of "respond" but 
see if the cache_peer connect-timeout option[1] is what you are looking 
for. That option defines "respond" as "establish a TCP connection with 
that peer known IP address". You probably want to mark those peers as 
parents and use the "first-up" peer selection algorithm[2] (which is the 
default).
