The Redemption period is a 30-day, Registry-imposed period that occurs when a domain name has been expired or not renewed. Normally domains would be deleted at this point, but the Redemption period provides the registrant owner one last chance to recover the domain before being dropped and potentially re-registered by someone else. Any website or email services associated with a domain name that has gone into a Redemption period will stop working because all DNS entries will be removed. There is an additional fee associated with purchasing a domain out of Redemption. If we are your sponsoring registrar, please feel free to contact us to buy your domain back before it is deleted.
