19 сентября 1990 года зарегистрировали первый отечественный домен верхнего уровня

Since the country was called the Soviet Union back then, the domain consisted of two English letters, S and U, which stood for the Soviet Union. Logically, the first Russian website was that of the Mathematics Department of the Academy of Sciences of USSR. After the dissolution of the Soviet Union, the former Soviet republics, which became independent states, received their own domains. The .su domain zone was frozen, but in 2003, registration in it resumed. So, the USSR lives – on the web.
