I sure it’s Spez.
i even notice downtime, so i guess who ever is attacking is doing a very shitty job lol.
Unless your account is on lemmy.world, you wouldn’t notice it.
Is this true even if accessing Lemmy.world from another instance?
Depends, your instance will cache content already retrieved but you’ll get errors when trying to interact or load updates. The same server instance talks both to clients and other servers.
The beauty of federation!
Turn the question back, actually. Do the DDOSers even think they’re achieving anything relevant, beyond being a bit annoying? .world is down from time to time, wow, how terrible. It’s not like I can’t log onto any other server and interact with world’s channels and threads from there, only to have my posts and upvotes become globally available as soon as world is back- Oh, wait, that’s exactly how it works.
The ironic part is that unless they have access to a botnet or are operating their own colo facility, they are probably paying more to run the attack than the target is.
Here is some useful information for people wanting to move instances. For a list of instances, along with with stats for those instances:

Who and why is attacking lemmy.world?
Pasting my comment from another thread.
From what I understand a user(Lmao/Angled) was “sub-lemmy camping” (took up thousands of popular sub names and wasn’t doing anything with them) so lemmy world banned him from that instance. He had a hissy fit and “vowed revenge” and has been attempting to do as much damage to .world as he/they could since. I can’t find the original post but https://old.lemmy.world/post/943832 and https://old.lemmy.world/post/1720870 has a bit of detail.
And that guy probably didn’t do anything with the communities and just hoarded them? What a donkey…
My guess is it was to weasel his way into having mod control over as many subs as he could in hopes some would take off. This happened in June around the time reddit was having their blackout protests.
Up to date post. https://old.lemmy.world/post/2923697
Doesn’t give much on who and why, more on what/how along with dispelling some myths.
Whoever is doing it is very quickly walking through a list of expensive queries to use in their DDoS attacks. Lemmy.world is playing whack-a-mole instead of proactively rate limiting/mitigating expensive queries. It may be that all their time is spent diagnosing and fixing with none left for proactive fixes.
The fact that the attacks are evolving and always hitting expensive queries implies that it’s a moderately skilled person/group familiar with the lemmy codebase.
You can speculate on motives as well as I can.
The net effect will be a more robust server and hopefully that code/knowledge is disseminated to other instances.
We are writing from an other instance account but yeah! You can do it!! 💪🏼
People, if an instance is crumbling, sign up to another instance! When you are able to use lemmy.world again, use lemmy2opml/lemmy_migrate (or any other tool that works, there’s a list on the Awesome Lemmy Github page) to migrate your followed communities to the new instance.
I don’t think the problem is much on the identification side, but on the communities one
Like, I can’t access any community on .world while the instance is down
You actually can, you just append @lemmy.world to the community name when accessing from another instance that’s federated with lemmy.world and once lemmy.world comes back up your contributions will be there. Any instance that’s federated with the instance your posting from will be able to participate in the discussion with you for that matter. The only thing you can’t do with a community when the host instance is down is subscribe to it. It would still get added to your subscriptions though if you try, the hosting insurance just won’t know until it comes back up and eats through the outboxes of federated instances to “catch up”.
Edit When it does come back up it’ll also get any messages that are in federated outboxes as well so your posts will ultimately show up on the host instance, just posted by your alt account
