.Mx

In 2009, the .mx ccTLD was rolled out in three steps:

• Sunrise period from 1 May to 31 July 2009, waiting period, registrants who have already registered any other .MX second-level domain were able to register their domain for one year
• Waiting period from 1 August to 31 August 2009, to set up the domains registered in the Sunrise period, and to resolve domain name disputes
• Initial registration period from 1 September to 31 October 2009; in this part the registration will be done with the policy first-come, first-served and only for one year with a special set of prices.^{[needs update]}
