Google's Usenet archive is too important to be owned by one company. My understanding is some Google engineers worked a few years ago to make sure Archive had a copy, but I can't verify that and I don't think it's online. Some of the earliest archives come from Eugene Spafford's collection which is readily online elsewhere, but Google did a lot of work cleaning it and of course has the DejaNews archives which are invaluable.

I'm amazed Google Groups still exists as a product, it seems abandoned internally and I expect to hear it's shut down any month now.
