For how long unbound caches failed queries? For now, if at the time of query the NSes are unreachable, unbound remembers that "reply" and returns "SERVFAIL" for that name for quite some time, even if the nameservers are now reachable again. To the extent that I have to restart it to clear the condition.
Note that the QUERY "result" (or lack thereof) is cached, not the nameservers. I.e., if I query another name in the same domain right when the NS becomes reachable, unbound will process it just fine. But the original query is still replied with SERVFAIL. unbound-1.2.1. Thanks! /mjt _______________________________________________ Unbound-users mailing list [email protected] http://unbound.nlnetlabs.nl/mailman/listinfo/unbound-users
