soc.octade.net is a Fediverse instance that uses the ActivityPub protocol. In other words, users at this host can communicate with people that use software like Mastodon, Pleroma, Friendica, etc. all around the world.
This server runs the snac software and there is no automatic sign-up process.
Problem:
You have a remote, headless computer that is running @tailscale and that needs to have its Tailscale binary updated. If you "ssh" into the host, and do e.g. "apt update; apt upgrade" when it comes time to replace the Tailscale binary you'll lose your TCP connection. The upgrade will happen but you'll lose the link and you'll just have to hope that you can get back in correctly.
Solution:
Use "mosh" instead of "ssh" to connect to the system that you want to update. It uses the same auth system as ssh but the actual connection is over UDP and it's very, very tolerant of temporary loss of connection. Losing the connection briefly does not interrupt the mosh session the way that ssh would drop.
I just now found a self-hosted fediverse server that allows connection and administration via SSH. So far its setup instructions are the simplest I've seen for any ActivityPub server software.

I don't know what's more stupid: #OpenSSH using different authentication flow depending on whether you have a `.pub` file in addition to the private key or not, or #GitHub suddenly starting to reject one of the two valid RFC 4252 workflows.

Oh joy, pre-auth libssh2 RCE.
Edit: fortunately it looks like sshd is not impacted, and it requires a malicious server for exploitation.
New #ssh key #randomart creature - now it's just ordinary #lemur hanging from branch, without any unnatural/fantasy features. It's tail was obviously visible in terminal.
