It’s a strange question, I know. Why would someone want to find a page that they knew didn’t exist? Right?

But the “not found” page for web sites can occasionally change, and earlier versions might have links to help a fat-fingered visitor get to the info they were looking for.

I doubt that it’s even possible, but thought I’d ask anyway. This subreddit seems to be full of clever folks who might have figured out a way.
