Looks like the .de ccTLD is the top global ccTLD again after .cn registrations fell. The latest figures for .cn domains are:
.cn ccTLD Registrations:
December 2009: 13,459,133
January 2010: 12,280,081
February 2010: 9,535,120
There was a low cost .cn domain offer running around the time of the 2008 Olympics which could have contributed to the fall in .cn figures but the change in .cn regulations introduced late last year may also have had an effect on renewals. That's approximately a 3.92 Million domain loss since December 2009.
