The Serbian National Register for Internet Domain Names has announced that after 21 years, the Internet website domain ".yu" -- representing the former Yugoslavia -- has become obsolete and been discontinued.
The group announced on its website that some 4,000 sites with the ".yu" domain name were shut down on March 30.
It said most of them had adopted the Serbian domain ".rs," which has been in use since March, 2008.
The ".yu" domain, adopted in 1989, was one of the last relics of an intact Yugoslavia before it fell apart in a series of regional wars during the 1990s.
