I think it has something to do with the actual h-y-p-e-r.space
server – attempting to just join a public room, “add server” results in the Element webUI red-error messaging “cannot get room list from server” and “cannot connect to server”. This matrix server doesn’t seem to show up on lists of popular, well known matrix instance so I think it’s maybe settings on their end. Admins should maybe have considered a “longstanding” server like tchncs.de
or whatnot if they didn’t want to use matrix.org. $0.02 https://servers.joinmatrix.org/

It looks like news@ and worldnews@ were spared, however both now show no moderators attached to them which feels a bit off. ( https://lemmy.world/c/news@kbin.social and https://lemmy.world/c/worldnews@kbin.social )
