Status codes

server delete prohibitedThe registry has blocked deletion, often during a dispute or investigation.
server transfer prohibitedThe registry has blocked transfers. This is not something your registrar can lift on its own — it is often applied for the first 60 days after registration or a previous transfer.
server update prohibitedThe registry has blocked updates. Usually a dispute, a legal hold, or a security measure on a high-value name.
