Can bind be configured to not drop RR's from the cache when the upstream DNS server is unresponsive

[Ron]

I did not mean forwarders, but I had a case where the authoritative name
servers for a domain were down
for an extended period of time, exceeding the ttl for their records. I was
curious if I could tell my DNS servers
to serve these records for longer than the registered ttl. And I wanted to
automate that.

But I'm afraid that's not gonna fly.
