You can renew at any time before your domain expires. The new expiration date will be extended from the current expiration, not from the date of renewal. We recommend renewing at least 30 days before expiration to avoid any disruption.
If your domain expires, it will stop resolving and your website and email will go offline. There is typically a grace period during which you can still renew, but additional fees may apply. After the grace period, the domain may become available for anyone to register.
Expiration reminder emails are sent automatically by the domain registry. Make sure the email address on your domain's contact information is current so you receive these notices.
