On May 1st, it will be possible again to register names under the .mx extension. The domain will be released in three phases.
1) The pre-registration period: This period starts May 1st 2009 and ends July 31st 2009
During this period the owners of a domain name under an Mexican extension (.com.mx, Org.mx, .net.mx,…) can register their name under the .mx extension. The domain name you wish to register needs to be exactly the same as your current domain name. If their are 2 applications for the same name (for instance someone has a name registered under the .com.mx domain and someone else has the same name registered under the .org.mx domain), priority will be given to the domain name with the oldest creation date. So if the .org.mx name is registered in 2006 and the .com.mx name is registered in 2005, the owner of the .com.mx name will receive the .mx name.
2) The quiet period: This period starts August 1st 2009 and ends August 31st 2009
During this period, no more applications will be accepted. The applications done during the pre-registration period which still have a pending status will be further processed.
3) The initial registration period: This period starts September 1st 2009 and ends October 31st 2009
During this period, everyone who wishes, can register a name under the .mx domain. During this period the first come, first served principle is applied.
