@cambridgeport90 @bjoern There's also https://mastodon.acc.sunet.se hosted at a Swedish university and as far as public instances I know the French government has https://mastodon.etalab.gouv.fr though I think it's only open to people with a gouv.fr email address, and from Brazil there is https://social.lab.cultura.gov.br which I believe is operated by or with support of their Ministry of Culture. (My Portugese leaves something to be desired.)
