Does anybody know of _any_ other TLD registry that is closing down for Christmas? I'd be interested to hear, if so.

I haven't heard any announcements of other ccTLD registrars closing down for the holidays. However, its is not unusual for operators of some ccTLDs and the sub-US domains to dissappear for days or weeks over holidays. Try to get a hold of sub-US domain registrars during the entire month of August in the US.
