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).

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
