Switzerland had a pilot project, but I don’t know what happened to it
I’m pretty sure there are more local governments with their own instances or plans to do it , specially after all the digital sovereignty discourse got some boost to it
I don’t think it is terribly expensive, a lot of (somewhat large) domain specific academic instances are maintained by grad students with donation from academics. As far as I know, many of them are in good financial standing.
From the top of my head, there are:
City of Amsterdam https://social.amsterdam.nl/
Baden-Württemberg https://bawü.social/
Netherlands https://social.overheid.nl/
Germany https://social.bund.de/
France https://social.numerique.gouv.fr/

There are several non-profit had their own instance, like ACM. I recall Mozilla used to do, but I am not sure if they still does.
How expensive is it to have your own instance?
