Lemmy World outages (lemmy.world)
submitted 1 year ago* (last edited 1 year ago) by lwadmin@lemmy.world to c/lemmyworld@lemmy.world
 

Hello there!

It has been a while since our last update, but it's about time to address the elephant in the room: downtimes. Lemmy.World has been having multiple downtimes a day for quite a while now. And we want to take the time to address some of the concerns and misconceptions that have been spread in chatrooms, memes and various comments in Lemmy communities.

So let's go over some of these misconceptions together.

"Lemmy.World is too big and that is bad for the fediverse".

While one thing is true, we are the biggest Lemmy instance, we are far from the biggest in the Fediverse. If you want actual numbers you can have a look here: https://fedidb.org/network

The entire Lemmy fediverse is still in its infancy and even though we don't like to compare ourselves to Reddit it gives you something comparable. The entire amount of Lemmy users on all instances combined is currently 444,876 which is still nothing compared to a medium sized subreddit. There are some points that can be made that it is better to spread the load of users and communities across other instances, but let us make it clear that this is not a technical problem.

And even in a decentralised system, there will always be bigger and smaller blocks within; such would be the nature of any platform looking to be shaped by its members. 

"Lemmy.World should close down registrations"

Lemmy.World is being linked in a number of Reddit subreddits and in Lemmy apps. Imagine if new users land here and they have no way to sign up. We have to assume that most new users have no information on how the Fediverse works and making them read a full page of what's what would scare a lot of those people off. They probably wouldn't even take the time to read why registrations would be closed, move on and not join the Fediverse at all. What we want to do, however, is inform the users before they sign up, without closing registrations. The option is already built into Lemmy but only available on Lemmy.ml - so a ticket was created with the development team to make these available to other instance Admins. Here is the post on Lemmy Github.

Which brings us to the third point:

"Lemmy.World can not handle the load, that's why the server is down all the time"

This is simply not true. There are no financial issues to upgrade the hardware, should that be required; but that is not the solution to this problem.

The problem is that for a couple of hours every day we are under a DDOS attack. It's a never-ending game of whack-a-mole where we close one attack vector and they'll start using another one. Without going too much into detail and expose too much, there are some very 'expensive' sql queries in Lemmy - actions or features that take up seconds instead of milliseconds to execute. And by by executing them by the thousand a minute you can overload the database server.

So who is attacking us? One thing that is clear is that those responsible of these attacks know the ins and outs of Lemmy. They know which database requests are the most taxing and they are always quick to find another as soon as we close one off. That's one of the only things we know for sure about our attackers. Being the biggest instance and having defederated with a couple of instances has made us a target.  

"Why do they need another sysop who works for free"

Everyone involved with LW works as a volunteer. The money that is donated goes to operational costs only - so hardware and infrastructure. And while we understand that working as a volunteer is not for everyone, nobody is forcing anyone to do anything. As a volunteer you decide how much of your free time you are willing to spend on this project, a service that is also being provided for free.

We will leave this thread pinned locally for a while and we will try to reply to genuine questions or concerns as soon as we can.

It's really annoying that it's down but I've found another instance to use when I'm not able to use this one. I hope you're able to stop these losers at some point. It's very frustrating what's happening but at the same time Lemmy is young and I think and hope it will be optimised so that it won't be a issue in the future.

Stay strong fellow lemmies, we're going to get trough this. For those of you that is very annoyed now: make a new account at some other instance. I've already got 3 accounts across 3 different instances already. Check what instance to join here: https://join-lemmy.org/instances

How do I as a developer:

  • contribute towards lemmy?
  • contribute toward the success of lemmy.world?

I’m an SRE by trade and would be happy to contribute my time in some way

There are quite a few InfoSec people here. While I have never held an official InfoSec job I do have a degree. However, my degree is debatable about whether it actually educates me as intended.

Point being there are a lot of people that have more knowledge than me as well as experience but I want to learn. As someone who is always listening to security podcasts like Hacking Humans or Darknet Diaries, naked hacking, or even InfoSec journalism around popular ongoing issues in the world like Click Here. I always want to learn and get experience.

I currently work in IT for a hospital. Is there any way to help with this kind of thing to learn and build on knowledge to help? To volunteer time to potentially see what is going on?

When will /u/spez just accept that he lost?

Ironic that they're effectively proving that you were right to not trust them...

[–] GnothiSeauton@lemmy.world 19 points 1 year ago

Would it be possible to have the error page when you are being attacked/there is an outage point to some other lemmy instances to go to?

I think that could be a big help if there is an issue when a new user tries to check out .world for the first time. They will at least have a link to click on to check out what lemmy is like on another instance and maybe sign up there too.

keep fighting the good fight <3

[–] desmosthenes@lemmy.world 17 points 1 year ago

keep up the good work team; you're the linchpin to this renaissance

[–] quinten@lemmy.world 17 points 1 year ago

Great explanation! And thanks for the many many hours you guys put in.

[–] ieightpi@lemmy.world 17 points 1 year ago (2 children)

Ive been waiting for this response from you guys. You have been a fantastic admin team so far. I still don't agree with some of the de-federating, but overall you guys truly show you care about this instance and the lemmy fediverse as a whole.

I know I wont be wavering because of butt hurt idiots in other instances. I will hold my ground and stick to Lemmy.World.

Keep it up and i hope that in due time, you guys can keep the DDOS attacks under control.

[–] samus12345@sh.itjust.works 15 points 1 year ago

There's nothing wrong with making an alt account for when .world is down. In fact, it's very much in the spirit of the fediverse to do so.

Is Lemmy not throttling requests to APIs based on how computationally expensive they are? Or is it that many IP addresses are hitting those APIs and are within the throttling limits?

[–] candybrie@lemmy.world 21 points 1 year ago (1 children)

The first D in DDOS means distributed, as in the requests are distributed across many different machines and IPs; so the second option.

Great work guys! Keep going!

[–] sverit@feddit.de 16 points 1 year ago (3 children)

Are DDoS protection services like those from Akamai, Arbor Networks, Link22 etc an option? Those are tested as ok by the German Federal Office for Information Security.

Question, can we configure the nginx to return cached responses for all non-logged in queries for predetermined periods of time? (1min for example?)
