Could you tweak your script that restarts squid to grab a copy of that page 
before the restart?

Something is causing all ICP responses to be dropped for at least 10 seconds, 
or whatever you have squids dead_peer_timeout set to. You could try setting 
dead_peer_timeout longer, perhaps 30 seconds, but not too long because this 
also affects how long squid will wait before noticing that a peer has shut 
down.

I'm still sure its not relevent, but have you tried this squid patch?
