Is there some definitive web statement that explains the fate of
all the historical Usenet archives (once of Dejanews) that were 
once available under Google Groups?  Where did their archive go?

This is as close as I found:

I think it's worse than that...  Never mind the complex searches...
A search for words that I know were once there now returns nothing.
