As well as ns.uu.net giving an upwards referral, ns0.ja.net gives
SERVFAIL. And sec2.authdns.ripe.net has the serial number problem
others have described. Also ns1.cs.ucl.ac.uk is still running BIND
8.2.3 and they refuse to upgrade (or so we were led to believe when
we first tried to register cam.ac.uk at dlv.isc.org in 2009 and ISC's
validation script went into a tizzy about it: as a more or less
direct result ns1.cs.ucl.ac.uk got removed as an official slave
for ac.uk).

Internationalism isn't looking too good, it seems...

What a good thing that ip6.int got transmogrified into ip6.arpa!
