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

[Darcy Kevin (FCA)]

By “upstream” I assume you’re talking about forwarders. If your forwarders are flakey, have you ever considered simply *not*forwarding*? That would seem to be a better, structural solution to your problem, than holding DNS data beyond its cache-expiration time (a really BAD idea).

                                                                                                                                                                                                - Kevin

Hi,

subject says all. Read manpages, could not find this in the FAQ's.
Hope this is possible. If not does anyone know of other name servers
that offer this option?

Thanks,
Ron Arts
