[dns-wg] Q: "lameness checks" - error messages for servers at the NCC?

Dear DNS-Folks, I'd like to understand whether receiving error messages that report problems related to the name server(s) run by/at the NCC is a rare case or rather "widespread". I am working on one such case now for a university served by our team. Please report back to me privately as I don't intend to see the list spammed with "mee too" messages :-) and I'll summarize to the list if useful. Thanks, Wilfried.
