I also have an account on another instance. The sole admin hasn’t been heard of for three weeks. There don’t seem to have been any mod actions for a month and the instance hasn’t been updated to the latest version.
At the moment I’m more concerned about the admin (I hope they are okay). But what would happen if they don’t show up? I guess eventually the instance would disappear without warning or be defederated if bad actors take over.
Is there anything built in to Lemmy that would allow a takeover if a big instance went under?
Mastodon has created a covenant that requires any participating instance to have at least two admins with access to the servers for these type of situations. It also requires instances to give three months notice in case the instance shuts down. Unfortunately it does not have any way to enforce it and there has been cases of admins that broke their pledge, but it does help in bringing some of the admins together.
