The error can occur in "normal" usage of BIND9 so may reflect a change in firewall practice or similar. It is occurring on recursive servers with no remote recursive queries allowed, so it is presumably in response to some query initiated locally (email/spam related perhaps?). We have spare disk space, I will enable query logging and see if it helps. Suggest the DNS ops list may be best place to take further comments. My best guess is ignorance over conspiracy. If I find a concrete answer I will follow up to NANOG if appropriate. Afraid my first attempt to investigate got side tracked into reporting some phishing scam or other.
