Greetings, draft-fans! I just exhumed the below-mentioned draft and recruited a co-author, since it seems like a timely topic for discussion.
This draft proposes a mechanism whereby an authority-server operator can signal to one or more recursive servers that the recursive server should flush a section of its cache. It's an in-band mechanism using TSIG-secured NOTIFY. No code-points were depleted during the preparation of this proposal. The use-cases are things like "prominent zone suffered some kind of signing error, things are better now, bad data is cached, would be nice to flush it" and "registrar suffered some kind of database error, things are better now, bad data is cached, etc." hence timely, above. Comments on the general idea or the specific proposal would be most welcome.
