> For archival purposes, I'd think everything is still in the internet archive?

I encourage anyone who thinks this is true to actually look for things in the internet archive and report back success. If you have the original exact URL you might be able to easily find something in the wayback machine, but if you have only a vague inclination that something existed and a general timeframe, it's a needle in a haystack. The wayback machine is, also extremely slow to retrieve data.
