Mastodon 4.5 running on FreeBSD 14.3-RELEASE with all major services seperated into different VNET Jails, different networks (different bridges, different l2-domains, firewalled by pf).
Did a little writeup about the infrastructure over at https://blog.hofstede.it/migrating-burningboardnet-mastodon-instance-to-a-multi-jail-freebsd-setup/
It's running extremely stable for 30 hours now, migration from the old (Linux) host was a full success!
And of course, everything implemented IPv6 first (It's 2025!) with IPv4+NAT only bolted on where neccesary for legacy-compatibility.
