It's interesting that while .yu was killed off, .su (Soviet Union) still exists and you can buy them today.
I would assume because the Soviet Union had a recognised successor state (being the Russian Federation), where as Yugoslavia did not have a recognised successor state.
Students Unions all over the world are very happy about that
Well, Russia is trying really hard to return to their Soviet Union days. At this point the old name is the only thing still missing.
According to an article from last year, .su might get retired by 2030
