My home instance is shutting down soon.
https://lemm.ee/post/65824884.
I am slightly unclear about what the instance admin meant.
Because of how Lemmy is built, everything posted on lemm.ee will still be accessible from other instances, even after we go offline.
How are other Lemmy instance able to access the content from the post-shutdown lemm.ee
?
Do all the other Lemmy instances keep a copy of the content from lemm.ee
?
If so, wouldn’t that be rather taxing on each Lemmy instance? (since they have to keep a copy of all the content from all instances they federate with).
I tried reading this up by researching on Lemmy federation, but this is still unclear to me.
When instances federate, they don’t send old content. Old content will be fetched if a user tries to open it, for example by clicking a link to an old post (on some apps) or pasting its url into the search box.
The data copied to the other instance will stay on the other instance, unless manually deleted for some reason.
