The end of a country code
.yu served Yugoslavia, and after 2003 the state union of Serbia and Montenegro. When Montenegro became independent in 2006, ISO 3166-1 assigned new codes — RS for Serbia and ME for Montenegro — and with them came .rs and .me.
Websites migrated over a transition period, and on April 1, 2010, .yu was removed from the root zone. It's a clean example of the normal lifecycle that .su famously escaped.

.yu by the numbers
.yu was the country-code top-level domain of Yugoslavia. It was retired and removed from the DNS root zone on April 1, 2010; its successor is .rs.
When a country code is removed from ISO 3166-1 — because a country changes its name, splits or merges — its ccTLD is eventually retired. Websites move to the new code, and after a transition period the old TLD disappears from the root zone.
