DNS Resolve dramas

Hi All,

Have had an extremely weird issue with my primary DNS server. All of a sudden it stops resolving domains names from the ROOT servers. I.E google.com will not resolve. 

The weird part is that there are no errors in syslog. When I perform the command host google.com it returns SVRFAIL. 

I know it is an issue with my DNS server (bind9 chrooted) but I can not determine where.

Extract of the top of my named.conf file

julian@ns1:~$ sudo cat /etc/bind/named.conf
// This is the primary configuration file for the BIND DNS server named.
// Please read /usr/share/doc/bind9/README.Debian.gz for information on the
// structure of BIND configuration files in Debian, *BEFORE* you customize
// this configuration file.
// If you are just adding zones, please do that in /etc/bind/named.conf.local

include "/etc/bind/named.conf.options";

// prime the server with knowledge of the root servers
zone "." {
        type hint;
        file "/etc/bind/db.root";

// be authoritative for the localhost forward and reverse zones, and for
// broadcast zones as per RFC 1912

zone "localhost" {
        type master;
        file "/etc/bind/db.local";

zone "127.in-addr.arpa" {
        type master;
        file "/etc/bind/db.127";

zone "0.in-addr.arpa" {
        type master;
        file "/etc/bind/db.0";

zone "255.in-addr.arpa" {
        type master;
        file "/etc/bind/db.255";

All my domain names still resolve fine. Just the domain names not hosted by my BIND9 will not resolve. 

Any ideas where I can start the investigation? I have even restored the named.conf file from a backup, but this does not assist. When I stop and start the service it resolves for about ten minutes, then stops.
