Grace period for .int.ru domain name?
Grace periods vary for country code Top Level Domains (ccTLD) including Internationalized Domain Names (IDN). Some registries require renewal up to 60 days in advance of the domain name expiration date. It is your responsibility to pay for your Renewal Fees in advance of the due date specified by 101domain regardless of the domain name expiration date. Failure to pay your Renewal Fees prior to the cpr144449003101 due date will result in a fee of $150 to renew your .int.ru domain.
There may be a restore period between when the domain expires and when the domain can be registered again. In the event that you do not pay by the renewal date, your site may be inaccessible during this time so it is very important that you renew this extension before the renewal date.
