What do you do when the Root records are wrong?

Not *quite* everything (e.g. not "net", which confused me before) - there
seems to be a short exclusion list including some (not all) TLDs.

I don't see any evidence that the servers for "net" are not all in
step and have the right delegation for udrtld.net, in which case such
changes aren't going to help at all.

Once a recursive nameserver gets the NS records pointing to
ns{1,2}432.ztomy.com into its cache, it can be hard to ever make
it let them go, other than by explicitly flushing the cache. This
is the standard "make sure your old nameservers stop serving the
zone, or at least serve a version with the new NS records in"
situation. but the (highly anti-social, by the way) behaviour
of these nameservers makes that impossible to arrange.
