It was a collection of silly quotes from IRC channels everywhere, many of which dated back to the 90s. It was rarely ever updated in the 2010s, but now, the URL no longer resolves.
Last capture was July 2023. https://web.archive.org/web/20230601000000*/bash.org
EDIT Someone archived all the quotes on the Internet Archive.
Probably is exactly what happened here. The FreeCAD wiki went down on the 1st too, thankfully they have it mirrored to a GitHub repo so that ended up not being a major issue
