Roland, you seem to be going off at a tangent. If you want to continue a discussion of what a "clueful" DNS user or robust DNS service means please take it to the DNS Working Group. Any definitions that emerge there can be fed into this WG. Assuming both WGs survive the heat death of the universe. :-) In the context of the document we're discussing here -- DNS blocking for government and regulatory people -- the point that should be made is that DNS service for some domain does not necessarily rest with a single entity. ie all the authoritative name servers for a domain might not be under the same administrative and operational control: SLAs, reporting and incident response procedures, legal jurisdictions, contracts, T&Cs, etc. Sent from a wee shiny thing with no keyboard that creates typos
