This will take place ~24 hours from now. Feel free to post and upvote questions beforehand in this post, as it will turn into the AMA tomorrow.
This is a chance for any users, admins, or developers to ask anything they’d like to myself, @nutomic@lemmy.ml , SleeplessOne , or @phiresky@lemmy.world about Lemmy, its future, and wider issues about the social media landscape today.
Back when the first Reddit exodus happened, there was a group heavily DDOSing many of the popular Lemmy instances. While it was a great opportunity to optimize Lemmy, did you ever find out who that attacker was?
I don’t think we found any specific groups of people attacking Lemmy. I personally just saw one or two what looked like individuals trying (and succeeding) to take Lemmy down with a few very simple requests that forced Lemmy to do lots of compute (something like fetching the next million posts from page 10000). The fixes for those were simple because it was just missing limits checking.
I’m not sure if there actually was a larger organized attack. Lots of performance issues in Lemmy simply appeared simultaneously and compunded each other with a rapidly growing number of active users and posts.
