Redemption is the status that most TLDs enter if they are not renewed in time.
When the domain expires, your website and mail service will stop functioning, and no changes can be made to the domain. If you do not renew the domain within the renew grace period, it enters a "redemption period" at the Registry and placed into the auction. Usually, domains are auctioned off successfully.
More details about domains' grace periods you can check in the "TLDs' grace periods" article.
If your domain is in a redemption state and you would like to reactivate it, submit a ticket or contact us via the Live chat providing your domain and account details.
If you have any questions, feel free to contact our Support Team.
