As soon as a domain name's registration is cancelled, a forty-day 'quarantine period' starts. For the duration of the quarantine period, the domain name cannot be re-registered by anyone except its last registrant. This page describes how a registrant can undo a cancellation during the quarantine period.

Undoing a cancellation

If your domain name's registration has been cancelled by mistake or without you asking for its cancellation, you can ask for it to be reinstated. The ability to reinstate a quarantined domain name means that minor errors don't have disproportionate consequences. You can ask your existing registrar to arrange the reinstatement or go to a new registrar.

Reinstatement of a quarantined domain name through a registrar

Your chosen registrar acts as an intermediary between you and SIDN. When we receive a request to undo a cancellation, we reinstate the registration in name of the last registrant. On reinstatement, the contact details for the technical and administrative contacts are the same as immediately prior to cancellation. If the domain name was secured with DNSSEC before being cancelled, the security is reactivated, provided that your registrar supports DNSSEC.

Cost of reinstating a quarantined domain name

We charge a fee to the registrar that reinstates a quarantined domain name. However, it is up to the registrar how much to charge the registrant. You therefore need to ask your registrar what it will cost to undo the cancellation of a quarantined domain name.
