I had some issues today because of these new f-roots.
The default FreeBSD named.conf suggests slaving . and
arpa zones from f-root. Not all the f-root servers permit
AXFR apparently, meaning that a lot of FreeBSD servers
can suddently stop being able to slave the root zones, if
anycast makes them hit a new non-axfr-enabled f-root
I've had problems getting AXFR from these, making me
think that all the new cloudflare nodes are refusing AXFR:
Wouldn't it be a good idea to keep axfr "rules" persistent
across all instances of a given root server?
I will contact the maintainer of the FreeBSD bind port
seperately and suggest using icanns axfr servers  as
default rather than f-root.
