BIND returns serverfail when querying for its authoriative domain

Hi there Serverfault folks!

First of all: sorry about the title, I had some problem coming up with the proper title.

I have a little home server set up, for internet sharing, samba, basic http, dlna mediaserver and what not, and I happend to have a domain at hand, so I thought why not direct it to this computer?

I have a BIND 9.8.0 installed, and - afaik - configured it properly.

For a few days, the public view did not worked, and I really did not cared, since the local view worked. But now suddenly, even the local view fails.

If I try to query the nameserver for anything in my domain, it returns the following error:

$ nslookup andromeda.dafaces.com
;; Got SERVFAIL reply from ::1, trying next server
;; Got SERVFAIL reply from ::1, trying next server
Server:         127.0.0.1
Address:        127.0.0.1#53

** server can't find andromeda.dafaces.com.dafaces.com: SERVFAIL

Also, the public view points to the old ip address of the domain, probably because of the same error.

Some information about the system:

$ uname -a
Linux tressis 2.6.37-ARCH #1 SMP PREEMPT Tue Mar 15 09:21:17 CET 2011 x86_64 AMD Athlon(tm) 64 X2 Dual Core Processor 5000+ AuthenticAMD GNU/Linux

$ named -v
BIND 9.8.0

And the named.conf file:

Edit:

Ohh, hell I almost forgot. Since the node is connected to the internet via a residential connection, there is a possibility, that the public ipv4 address will change(but thank god, it is a very rare case), so I daily update the external IP address in the zone file with a shellscript:

# cat /etc/cron.daily/dnsupdate
#!/bin/sh

FILE="/var/named/external/dafaces.com.fw"
SERIAL=$(date +%Y%m%d05)
PUBLIC_IP=$(ifconfig internet |sed -n "/inet addr:.*255.255.255.255/{s/.*inet addr://; s/ .*//; p}")

cat $FILE | sed --posix 's/^.* serial$/\t\t\t\t\t'$SERIAL'; serial/' | sed --posix 's/[0-9]*\.[0-9]*\.[0-9]*\.[0-9]*/'$PUBLIC_IP'/'  > /tmp/ujzona
mv /tmp/ujzona $FILE
/etc/rc.d/named reload
