Imagine your life is so worthless that you decided to ddos a feddiverse instance
I mean it could also be someone that was hired to do it. You know getting rid of the competition before it becomes a real competitor.
that doesn’t make their life any less worthless
wait how does the motivation for it not affect that
They’re a nuisance, but are proving the benefits of a decentralized system more than anything else.
And also battle-testing Fediverse infrastructure to make it more resilient in the future!

Actually is quite easy to image.
…if someone pay them to do so.
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.
If .world is down, can you still interact with it from other instances?
Each instance keeps a local copy of the communities they’re federated with. Users of that instance interact with the local copy, and instances communicate with each other to tell what’s going on.
This means that, if .world crashes at 5PM, and you have an account on lemm.ee, you can go to lemm.ee’s local copy of world->worldnews, find a thread started at 4PM, comment on it, and other lemm.ee users will see and upvote/downvote your comment.
When .world is back on at 7PM, lemm.ee will tell it: “Hey, Cold_Brew_Enema said [Thanks a lot for the gold kind stranger] and got 6 downvotes”, and .world will update the thread with your comment and downvotes for users of all instances to see.
This is my understanding of how it works, and I’m not familiar with the actual code, but it seems to be close to reality.
Excellent thank you!
There may be some things that don’t get synced if the instance holding the pending federation messages also goes down or restarts because AFAIK they are stored in memory, not in persistent storage.
I’m not sure it works like that but it makes sense that way.
You can log into non-world instances using world credentials?
No, you make an alt-account on a non-world instance and interact with world communities from there. The only issue is that you aren’t carrying over your subscriptions and blocks unless you use a special tool, about which I don’t know much.
I tried figuring out how to use the Lemmy API to subscribe to all my subscriptions from my kbin account a week or two ago
I remember getting stuck and giving up, so I think I’m going to do it semi-manually or something later on, unless some kind wizard blesses me with the name of such a tool
There is a script for it, I’ve been meaning to use it and create couple of alts but haven’t done yet.
Lasim works very well.
+1 for LASIM
No. It’s basically like signing in at another e-mail provider. Instead of asdfasdfasdf@yahoo.com you now have asdfasdfasdf@hotmail.com and can from then on e-mail the same contacts. Just with posts, threads and comments instead of e-mail of course.
Just make another account, you can usually even use the same username cuz there’s so many instances out there.
Unfortunately no. I don’t understand this well enough to know why accounts don’t sync, but that seems like it would be much better to me.
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
Removed by mod
are they stored on whatever instance I am registered on and then synced to lemmy.world once it’s up?
Yes
Ok but how other people will know I replied to a comment or posted if the community on the original server is down?
They’ll get it when it eventually comes back up
Ok but the question that arise is:" if the community is duplicated on every server that access it, isn’t it a little bit of a waste of computational power and disk space ?"
Expecially considering now Lemmy is pretty small, but in the future you could hopefully have a much larger audience
Ok but how other people will know I replied to a comment or posted if the community on the original server is down?
Not sure if other instances can communicate between them to get updated before the original server is up again and everything gets updated.
I sure it’s Spez.
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.
What a fucking donkey
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.
🤣 What a sad sad existence. Fucking donkey.
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.
Some people are so sad lol
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.
The beauty of federation!
Here is some useful information for people wanting to move instances. For a list of instances, along with with stats for those instances:
https://fedidb.org/software/lemmy or https://lemmyverse.net/
Also, tools for migrating instances:
https://github.com/CMahaff/lasim (easy) - Latest Version Download (just select your OS type and run the program)
We are writing from an other instance account but yeah! You can do it!! 💪🏼
I don’t know if it’s ddos attacks or if it’s a “lemmy hug of death” way to many users overloading the servers network, we need a bigger Internet pipe?
The site usually works for me during off hours early morning usually best.
I really don’t get the sense that Lemmy is being overwhelmed by users. Things be pretty quite in these here parts. If this kind of volume is bringing down what I thought was one of the main instances, Fediverse seems kind of doomed. I’ve long been worried about scalability. I’ve tried other instances and had issues. Each time I think should I give up or hop instances, make a new account etc. People will flock to the biggest most stable instances, but if they can’t afford fancy hosting, everything starts to crumble
It’s a DDoS https://old.lemmy.world/post/2923697
@ekZepp This just made me rewatch that scene. Thanks!
