If you did not place your renewal before the expiry date of the domain and the registry suspended resolution, then once a late renewal/restore is placed there may be a delay before the domain begins to resolve from all locations again. Please note also that late renewals/restores do often take longer to process than normal renewals as there is usually an entirely different procedure needed for us to bring your domain back from its expired status.
Please be aware that if your domain expired some time ago we may not be able to restore your DNS settings so you will need to log in to your account and add these back in.
