Do they get adopted by other instances? Are they still accessible from other instances? Can you still post on them from another instance?
Edit: From my understanding every instance that deals with a community has a cached copy. Will that copy disappear after a certain time, because it can’t phone to home anymore?
The modern-day equivalent of “what happens to a dream deferred?”
I wonder if the activitypub protocol (or, if not the protocol then some other layer) allows for the idea of “community mirrors”. The way that the protocol works at the moment, as I understand it, only the host instance has a complete record of a community’s posts and comments. But if there was a way for a community to designate one or more other instances as “mirrors” which maintain a complete sync of a community’s content (going back all the way to the community’s founding), that would lower the exposure to instances going down.
There would need to be a process (both technical and administrative) for a mirror to be designated as the new host instance should the original host disappear.
This would build in additional resilience into the fediverse model, by taking advantage of its distributed nature.
Just started learning about the fediverse but I suspect everything goes down with the ship. Sort of creates a development opportunity for community driven backup utilities, though. Interesting problems are fun development challenges :)
I’ve been wondering about this also since I started a new community in the last week and have already invested a fair amount of time into it. I’m hesitant to keep investing time and effort, though, if it can just disappear with no recourse.
As of Lemmy 0.18.1, cached copies on other instances do not disappear if the original instance has died.
In theory, it might even be possible to actually clone a cached copy into a new local community. This would require some database hacking, so not recommended unless you’re familiar with Lemmy code and SQL.
Not sure how it is on lemmy. But looking at the structure on kbin. I reckon you could (with a little sql magic) convert the existing one to a local magazine without cloning, and then people could subscribe to the new version or existing subs could also hack their sql to change the id to match the new instance and toggle the subscriptions.
On Lemmy though I think images are not cached locally. So you might lose those. Kbin by default will also download images/media locally too.
Not sure this would happen enough to add formal functionality for it though.
