It did slowly sneak in over time I guess. In my last year of my master's eventually the faculty was forced to stop hosting its own intranet and mailing lists and migrate everything to the "cloud" (Microsoft 365 and Blackboard).

I have a copy at home of all the old wiki content and the old cs.uu.nl website. The university themselves didn't even think they should archive it so I archived it myself.

I hope there's other people with copies too. My archive isn't complete
