https://med-mastodon.com is now back online!
Their host provided me the following updates:
- the owner is allowing transfer of ownership to someone else
- it looks like it has been transferred to Ryan Wild (@wild1145), who also runs MastodonAppUK and Universeodon, so I'd say it's in very good hands: https://mastodonapp.uk/@wild1145/115844028613413319
- it will be online for the next 30 days at least
- Update: Ryan replied and said "no plan for it to be cancelled now so folks are safe to keep their account"
I recommend exporting/backing up your data within the next 30 days.
