    lib/resolve: penalize failing NSs · 01ee9f37

    any answer that is considered as malformed/servfail/otherwise bad
    penalizes the NS for the next time like timeout, this doesn't apply for
    DNSSEC validation failures as it still may be okay for insecure
    resolution. EDNS failures are okay because the server is requeried in
    the most simple RFC1035 mode before flagging it as failed
    this avoids instant requeries for SERVFAILing resolutions
