You can also check with /instances endpoint i.e.

lemmy.world/instances

Maybe some content in cache. Not photos for sure. I’m not sure how exactly will this look like, but we can observe vlemmy.net as example, as it seems to be permanently down.

Only thing that bothers me is that most of the biggest communities are @ lemmy.world or lemmy.ml, so it still feels kind of centralized.

Obviously it’s not, but I wonder if too much “power” in one instance will have some negative consequences in future. For example one of them going black results in losing half of lemmy content and orphaned users probably won’t spread to smaller instances but will join next biggest.

Of course it may. There is a reason why openai outsourced cheap Kenyan workers to filter data.
