How-to: (if ISP dns server down) go direct to root

Run bind 9.1.2 with an internal and an external zone.

Frequently, now days, my ISP servers crash and my two dns
servers fail to provide external name resolution during those
lapses.  My servers remain visible to the outside, because I
switched to Netsol for my domain's external dns.  However, I am
now blind internally and end up having to go to tracert.com
(/etc/hosts) for manual name resolution...

Question, I do have a "." zone and db.root defined, but no joy.
How do I get bind to feed its cache from the internet root
servers, when my ISP forwarders are down???

TIA
tonyb
