I saw that messages have different identifiers on different servers. What should I write in my text to make the hyperlink to work on all servers?

15 ≠ 49064481

The site https://lemmy.ml/ is unreachable from my computer because of government politics. I want to refer to the copy of message, which is downloaded into my instance. But it have a new ID in my DB.

You can also paste that into the search of any lemmy instance to find it, if they mirrored it

Yes, this works. But I don't understand how. The question is - will it work, if remote instance went down?

Once a user on the remote instance subscribes, all posts are replicated over as they're made. Not at the the time of request.

The existence of local replica doesn't prove, that searching by remote URL will work (with remote server down).
