The .es registry, Red.es, has become aware of a number of domain names in their registry with inaccurate Whois data following an audit of registrations.
Currently Red.es is contacting registrants and administrative contacts informing them they have 30 days to update their contact information. During this period they are also phoning registrars and administrative contacts informing them of the notice sent and the requirement to update their registration data.
At the end of the 30-day period, if errors have not been updated, Red.es will initiate a Special Cancellation Procedure, details of which are available in Spanish here. An English version is available here, but from my experience itâs better to use an online translation service (Bing or Google).
