Wikipedia claims Yuri's page lasted for "3 years, 7 months"

How do we know if that is true? I'd trust the article's diffing history, though. But that is gone - just as the text of the article is nowhere to be found.

The article was moved from its original location to https://en.wikipedia.org/wiki/Wikipedia:List_of_hoaxes_on_Wi... . Its edit history is intact there; click "View History" at the top there to see it.
