It's sort of a bug in squid. Basically your sibling has restricted
miss access (which squid.conf implies is ok), but then causes this
problem, for roughly 1-2% (from my experience) of what your sibling
claims to be a hit. Looking at my stats, as far as I can tell it
is thought to be a hit via UDP, but then when it is actually fetched
with TCP squid decides it's stale, checks the orignal source and
decides it needs to be refetched and it is now a miss, and denies
you. The fix it to not restrict misses to siblings.

PS: You might want to put in your "local_domain" in squid.conf, so
that parents/siblings aren't used to access your local servers.
