I see. I attacked the wrong server :)

As long as there are no key records in the root this kind of attack
does not make sense on a rootserver.

Just an aside. Looks to me like splitting UDP and TCP servers might
be idea. Either via firewall or like tinydns / axfrdns from the
djbdns packages. Now axfr would no longer impact the udp nameservers.

Even if the TCP servers take much longer, the clients will wait.
The time does not matter because there is no user on the slave.
On the other hand the slave will answer much faster because
it is local to its clients.

Kind regards
