There was a case not long ago where someone decided that it was a good
idea to change the NS records in lame domains. This caused a major
service outage for a company who needed this specific domain to be lame
in order for a certain service to function. Fortunately, we were able to
find the domain technical contact who was able to log into the registrar
and put the lame delegation back. Now, the problem has been solved by
moving the domain to another registrar whose goal is to keep things the
way they are, not clean up lame domains or other perceived errors.
