Interestingly, Kosovo is in multiple organizations that fall under "UN Specialized Agencies" (IMF, World Bank, etc.) and as such should have received a ccTLD over 10-15 years ago as per the UN's rules.
Instead, they have to keep the temporarily assigned .xk which the UN confirmed can never be a permanent ccTLD.
What is going to happen to all .xk sites once the UN finally gets around to publishing the bulletin on Kosovo's country code?
