Ah... I thought this might be the case (using the same DNS cache for the
hosts in squid.conf as for normal lookups). 6 hours is fine for me (I
don't think UKERNA are going to change our caches around that much...
although I guess they might if some machines die... in which case, in
light of this information, I'd expect them to inform me (nudge nudge!)).
Thanks,
