In section 2.2.1, the draft says: [...] Implementations that perform lame server caching MUST refrain from sending queries to known lame servers based on a time interval from when the server is discovered to be lame. [...] In general, I agree on this recommendation. But it might cause a rather undesirable result when all authoritative servers seem to be lame, since some authoritative server implementations can be lame for particular resource record types. (See Section 4.4 of draft-ietf-dnsop-misbehavior-against-aaaa-01.txt for more details) Of course, what is wrong here is "lame" authoritative servers. But sometimes we need to explore workaround to deal with real-world's problems... Meanwhile, I'm not sure if the recommendation also applies to the case where *all* authoritative servers seem to lame. In the beginning of Section 2.2, the draft says as follows: A more common occurrence is a subset of a zone's name servers being unavailable or misconfigured. But I could not be sure if this section (including the recommendation) only concentrates on the case where a subset of the servers behave badly or it also considers the case where all of them are bad. If the intention is the former, then please make it clear throughout the section, particularly in Section 2.2.1. If the intention is the latter, I hope the document also notes that the recommended behavior may sometimes cause undesirable result while the behavior generally makes sense.
