Welp that answers a lot of why all .ml are down(i.imgur.com)

I don’t think either of these signature options for Server to Server communications means that my current lemmy.saik0.com instance can’t be torn down (delete LXC container) and reconfigured as a brand new instance (New LXC container) and other instances wouldn’t know that there’s been a change to the instance running here… or more accurately would flag a change. I think these signatures are all about not being able to spoof OTHER instances. eg, lemmy.ml can’t send messages on behalf of lemmy.world.

I assumed that once federated the public key would be remembered and signatures that do not match it would be handled, but you may be correct. I do wonder whether this could be a problem as instances close down over time. I’ll have to spend some more time researching to see if there’s a more clear answer, or if any ActivityPub implementations have their own way of handling that situation.
