For gTLDs, after expiration we allow the domain owner 30-35 days to renew the domain. If it is not renewed during this period the domain gets deleted and the 30 day’s redemption period will start just after this. During these 30 days the domain can still be restored by the current owner by paying the redemption fees. If it is not restored it will then go into a ‘pending delete status’ at the registry for another 5 days and it will then be released.
