“ICANN Reviews Revoking Outdated Suffixes” (HT: Slashdot).
From the piece, “The Soviet Union’s ‘.su’ is the leading candidate for deletion.” A Google search turns up about 3 million sites with the .su suffix.
How exactly did the Soviet Union get a domain suffix? The Soviet Union collapsed in 1991 and wasn’t yet highly commercialized. But it seems that the administrative record for the .su suffix was created just in time, on September 19, 1990, a little over a year before the formal dissolution of the union on December 8, 1991.
