We only accept delegations and updates when the servers are correctly
Weekly we recheck de delegations, keep a public report at whois, and
every two weeks report back on lame delegation cases.
We don't undelegate lame domains but we continue to notify them.
This policy brought our lame delegations to 9% of our zone data. See
http://registro.br/stat/dns.html for historic data.
