I can't think of anything off the top of my head. Are the sites
that are transferring repeating this act, or is this just a lit of
random sites around the world?
Do any of the DNS diagnostic tools, like dnswalk, zone-transfer a
domain?
I've lately been getting a weekly email from someon in .nl about
a lame delegation problem; the secondary server my ISP chose is
ont responding. They're moving secondary services to a server they
own at a co-locate site, in the meantime, I'm lame. ;^) Perhaps
the diagnostic software that discovers these problems does zone
transfers to get the scoop on the domain?
Best of luck.
