Recent activity shows as the fediverse ages many servers will continue without issues, however, some have been abandoned by their admins, but not unplugged.
Everyday users shouldn't be burdened with admin or mod issues, but maybe it's good to keep a casual eye on the health of your server by doing any of the following occasionally:
Check the admin is active on the system
Check the server gets software updates
Check your local server timeline to see what content is posted, what's permitted on the server, if there's content that should be moderated but isn't
If your server passes the health check, great!
If it raises doubts consider investigating more 🙏
