I don't know how bind does resolve but we are doing the right thing here, we get a delegation to two NS (mail1.alestra.net.mx. and dns.alestra.net.mx.) for s-s.mx. from the mx. zone, and both of these servers fail to respond to the first request we send to them. There is nothing else to try but return a SERVFAIL. This zone is broken and needs to be fixed.
I have a vague idea that bind retries each server a few times, rather than giving up on one attempt to each.
<looks around> Hmm, RFC1536 talks about this. _______________________________________________ Pdns-users mailing list Pdns-users@mailman.powerdns.com https://mailman.powerdns.com/mailman/listinfo/pdns-users
