It’s amazing how fast people can fix lame delegations once email and other services stop flowing. The only reason you think it is un- winnable is that you are unwilling to remove the delegation for failing to maintain a properly working configuration. Start removing lame delegation after fair warnings and you will see others fixing their lame delegations on initial notice. No system works if there are not checks and balances. -- Mark Andrews > On 4 May 2018, at 01:05, David Huberman <david.huberman@icann.org> wrote: > > Ed Lewis wrote: > >> (Only if you like reading history:) > >> The reason was a flaw in "certain old resolvers" that followed the "upwards referral" to the root that >> the "predominate server code of the time" had decided to use for lameness..
