-Subject: [PATCH] resolver.c: Prevent SERVFAIL from marking name server bad
-
-A name server that returns "Server Failure" is indicating only that
-the server couldn't process that particular request. We should NOT
-assume that the name server is incapable of serving other requests.
-
-Here's the scenario we've been encountering...
-
-* 2 local name servers configured in resolv.conf.
-* An OPTIONS request causes a request for A and AAAA records to go out
- to both nameservers.
-* The A responses both come back successfully resolved.
-* Because of an issue at some upstream nameserver, the AAAA responses
- for that particular query come back as "SERVFAIL" from both local
- name servers.
-* Both local servers are marked as bad and no further queries can be
- sent until the 60 second ttl expires. Only previously cached results
- can be used.
-* In this case, 60 seconds is just enough time for another OPTIONS
- request to go out to the same host so the cycle repeats.
-
-We could set the bad ttl really low but that also affects REFUSED and
-NOTAUTH which probably DO signal a real server issue. Besides, even
-a really low bad ttl would be an issue on a pbx.
