Hi Warren and thanks for your reply,
I've dug around some more and identified the problem we've been having.
Apparently, from a given netblock, we can't AXFR the "." and "arpa"
zones anymore with F.ROOT-SERVERS.NET.
We can from some other boxes.
I suspect we might have been firewalled or something, although we
don't query them very often , but that's beyond the point.
I've now transitioned all our PF boxes to slave from
"xfr.lax.dns.icann.org" and "xfr.cjr.dns.icann.org" as per the
documentation found in /etc/namedb/named.conf
What bothers me is that the commented lines from named.conf say to use
the ICANN XFR servers, while the actual commented configuration uses
F.ROOT-SERVERS.NET
See below a freshly SVNup'd copy on 10.0:

I SVNup'd it just today, and yet:
===
As documented at http://dns.icann.org/services/axfr/ these zones:
"." (the root), ARPA, IN-ADDR.ARPA, IP6.ARPA, and ROOT-SERVERS.NET
are available for AXFR from these servers on IPv4 and IPv6:
xfr.lax.dns.icann.org, xfr.cjr.dns.icann.org
*/
/*
zone "." {
type slave;
file "/etc/namedb/slave/root.slave";
masters {
192.5.5.241; // F.ROOT-SERVERS.NET.
};
notify no;
};
===
I'm going to file a PR with a small diff to use the ICANN's XFR
servers instead of F.
Thanks for your feedback regardless :)
