Are the registry procedures causing the problem? Since most of my communities are on lemmy.ml, wouldn’t I still be using lemmy.lm’s bandwidth? Or is it more crucial to ensure that the communities are distributed more evenly across different instances?
I would add to this community migration, which will be important as instances start going offline. User migration is great, but, whereas on Mastodon, the content lives on the user, I believe here it lives on the community.
