Your domain name has been deactivated by Afnic as a result of a problem. Deactivation entails the deletion of the corresponding DNS registration which enabled the link to your Internet resources. A blocked domain name is still published in the Whois directory and still belongs to its holder, but any operation, even back-end, is prohibited during the period of blockage. To find out the reasons for the blocking and how to get it unblocked, contact your Registrar as soon as possible.
