There will be a lot of lemm.ee/p/123 links around. As far as I understand, any server that federated with lemm.ee (e.g. lemmy.world) will continue to host the federated communities and posts forever.

So here's my proposal. We build a simple tool that says, when you visit lemm.ee/p/123, we check if that post exists on lemmy.world and forward you there. Doesn't necessarily have to be lemmy.world. We could even present the user with multiple instances to resolve the post from.

If you're interested in how this would work, it would utilize the resolve_object endpoint, which both Lemmy and PieFed implement.

Here are some examples of how you can still look up lemm.ee posts via the API of other instances:

For this to really work smoothly, whoever owns the domains of the shut down instances would have to host this tool (e.g. lemm.ee would have to host it at lemm.ee). I have no idea how to get in touch with whoever owns the domain, but I would be happy to help build this.

What if an instance wants to disappear?

Edit: Oh, I see, this would be a service provided by whoever owns the shut-down domain.
