We were looking at a post of an Einstein experiment from last year (Geertruida de Haas Lorentz) where we had a pointer to our favorite site (This week's finds in mathematical physics) which goes way back and carried forward the older formats which was nice to see.
But, it was updated to be modern (Azimuth) and hit the site when it was reporting that database updates to remove DEI material was throwing away research results that were the motive for the internet, to begin with.
Through time, archive org has tried to make backup copies of sites. Imagine that being done real time. Well, it is not, so things are turning up missing.
Not going into details, yet, there are a couple of thoughts relating to humans and their behavior (think of anthropology). For one, the "cancel culture" seems to be universal, or as one TV show used, voted off the island. Another might be that some edits would be the equivalent to book burning. Or, notes being thrown away.
We learn in the lab to use a method to allow traces for various types of analysis.
Unfortunately, the web has evolved badly from its inception as the recreation of the wild west of the U.S. with lots of arguments being made that maintenance is not possible.
Well, we see this side effect of recent vintage.
