Two letters TLD like .io are ISO country codes. Catalonia’s .cat is a generic TLD in comparison. Since .io stands for the British Indian Ocean Territory and Chagos Island isn’t going to be ‘separate’ anymore by becoming part of Mauritius, IANA’s logic is that the ccTLD has to be retired. That .su is still around after the collapse of USSR isn’t a valid argument for them.
I don’t get why they killed it. some regional areas have their own TLD. .cat for Catalonia, for example.
