I noticed that for a week or so now the community has been much smaller tham it used to be. I’m seeing an almost 90% decrease in posts, comments, and votes. Did something get defederated or did a big community go down? Lemmy stats show that Lemmy average user count is still about the same.
@db0@lemmy.dbzer0.com did a great job with that post mortem and showed up a lot of places where federation could choke. Seems there is not much troubleshooting information easily available for lemmy admins, i hope it helps.
