.sx is the country code top-level domain (ccTLD) in the Domain Name System of the Internet for Sint Maarten.
Sint Maarten became an autonomous country within the Kingdom of the Netherlands on October 10, 2010. On December 15, 2010, the ISO 3166 Maintenance Agency allocated SX as the ISO 3166-1 alpha-2 code for Sint Maarten, as other possible combinations such as .sm, .ma, and .mt had already been allocated.
The sx top-level domain is run on the CIRA Fury Registry Platform. Registrars of sx domains must be accredited by the registry.
After an initial sunrise period to claim trademarked names, and registration periods for local priority, and landrush assignments the registry opened general availability registrations to the public on 15 November 2012. A local presence is not required of domain name registrants.
