Anyone maintaining a Mastodon instance and losing sleep over the Great Migration should read this excellent technical discussion of the matter: https://nora.codes/post/scaling-mastodon-in-the-face-of-an-exodus/ This is also a really good description of the sort of problems we're confronting with the backend of hcommons.social (and some of the things we've tried), if you're interested. Good times are ahead, though! We have a dev instance that is a lot more powerful than the one that is running right now.
