I'm seeing zero comments come out of Lemmy.world in the past 15 minutes, app users shouldn't have been redirected... and users commenting from other servers should be going to communities homed there. I wonder if they shut off federation. I normally see over 10 comments a minute: https://lemmyadmin.bulletintree.com/query/comments_ap_id_host_prev?output=table&timeperiod=15
Last post received in my instance from them was over an hour ago. I usually see one or two a minute. Comments stopped at the same time and those are usually about every 5 seconds.
Hmm. They seem to have cleaned up a lot of things by now. If federation is an issue that might something the hacker did? Though pausing federation as a precaution makes sense.
