Of you post to an outside community, is not hosted on your insurance. It's hosted where it's posted.
I don't think that is actually true...
OK let's make a test. I have 2 accounts on sh.itjust.works, this is my lemmy.fmhy.ml account. I'll attach a pic, see where the link points to.
The link says lemmy.fmhy.ml ๐คท.
Huh. Well that just makes no sense structurally. Thanks for pointing it out though.
How does this thing work at all? You would expect it to all be hosted to the site the community is hosted on. So now when a comment thread is fetched, it has to go to all these other servers for every single comment from another instance. This is actually mind-boggling.
Does anyone have an ELI5 for why it's done this way?
Actually, the post content is saved on the instance where the post is posted as well. That post is called a copy, the original resides on the poster's originating instance. But, not the media, no, that resides on the instance where the poster resgistered.
