So after we've extended the virtual cloud server twice, we're at the max for the current configuration. And with this crazy growth (almost 12k users!!) even now the server is more and more reaching capacity.

Therefore I decided to order a dedicated server. Same one as used for mastodon.world.

So the bad news... we will need some downtime. Hopefully, not too much. I will prepare the new server, copy (rsync) stuff over, stop Lemmy, do last rsync and change the DNS. If all goes well it would take maybe 10 minutes downtime, 30 at most. (With mastodon.world it took 20 minutes, mainly because of a typo :-) )

For those who would like to donate, to cover server costs, you can do so at our OpenCollective or Patreon

Thanks!

Update The server was migrated. It took around 4 minutes downtime. For those who asked, it now uses a dedicated server with a AMD EPYC 7502P 32 Cores "Rome" CPU and 128GB RAM. Should be enough for now.

I will be tuning the database a bit, so that should give some extra seconds of downtime, but just refresh and it's back. After that I'll investigate further to the cause of the slow posting. Thanks @[email protected] for assisting with that.

I hope not all people will go back to reddit as soon as the communities go public again.

The two day blackout was what finally got me to actually look into the fediverse, figure out servers and whatnot, and make an account to try it out. I've been meaning to look into it for a while, but the blackout was the push I needed. I'm sure I'm not alone. I'm far more interested in exploring this exciting new space then I am going back to the garbage filled Reddit, even if they miraculously back down on the API changes .

My reddit account was over 10 years old. This is my first comment on Lemmy/Fediverse.

[-] [email protected] 3 points 1 year ago

Relate. 12 year account, would like to see this take off. They're not changing.

[-] [email protected] 13 points 1 year ago

I will stay here. Did not have this feeling of internet independence for a very long time. I'm done with Reddit.

[-] [email protected] 10 points 1 year ago

I know I won't!

[-] [email protected] 10 points 1 year ago

I don't plan on it. RIF was my main way of browsing Reddit so once that goes, that's pretty much me done. I'll probably still peruse sysadmin for work purposes, but my Reddit time will become Lemmy time.

[-] [email protected] 9 points 1 year ago

I'm just gonna browse both for a while I guess. I know I'm not downloading the official app on my phone though

I am in a transition period where I still keep Apollo installed, and trying to find enough communities here in order to be somewhat ready for the July 🙈

I have deleted nearly 10 years worth of content and account already. Those leaving should do the same.

[-] [email protected] 5 points 1 year ago

I'm more or less getting what I wanted out of reddit out of lemmy already. There are a few teething pains, but overall it reminds me of the nice little community we had at reddit in 2007. It got better and better until about 2012 after the big digg migration where it started to peak and devolve. I would love to relive those first 5 years here again. I don't miss reddit at all.

[-] [email protected] 17 points 1 year ago

I'm not an engineer or a dev - but requiring a 32-core, $2000+ CPU to support 12k users doesn't seem like it would scale well. Is this normal, or does the fediverse require more computational resources than a simpler setup like reddit? How would a fediverse instance with 100k users be maintained?

[-] [email protected] 18 points 1 year ago* (last edited 1 year ago)

Look at the pricing!

Hetzner wants 150€ for this server. 3TB disk is 50€ extra. So 200€ for the server per month. This is also about 200$ so 1.6¢ per user and month. This should be very manageable.

Also it doesn't mean the server only holds 12k users. If the server holds 20k users or more you Look at less than a Cent cost per user and month.

They are already raising 600€ per month via Patron only so 3 months worth per month. If the server gets bigger, more people will probably give money and while it stays a kinda hobby project it should work out fine.

But you are right with something else:
Lemmy currently has no ability to loadbalance over multiple servers for one instance. This will become a Problem in the future, but it is being worked at.

[-] [email protected] 14 points 1 year ago

Reddit is not a "simpler setup". Reddit has gigantic amounts of computational resources to throw at things. Resources that make servers like this look like a Raspberry Pi. They're just much less transparent about how the backend works and what they have.

[-] [email protected] 10 points 1 year ago

Was thinking the same thing, is a lemmy instance supposed to be literally a single server instance?

[-] [email protected] 6 points 1 year ago

I'm also interested in the answer to this question.

[-] [email protected] 16 points 1 year ago

King Ruud is good to us

[-] [email protected] 12 points 1 year ago

Like many others, I came from Reddit and was initially hesitant to try it out, but I love this place so much! It really feels like the "worse" parts of Reddit have been skimmed off, and that definitely shows with how nice people seem here! Thank you so much!

[-] [email protected] 10 points 1 year ago

Truth is for me as someone who used Reddit for about the last 16 years, it very much feels like the early days of Reddit again.

Which is a very good thing, because that's what I originally signed up for compared to a metric fuckton of karma farming spam bots.

I just hope it gains enough traction to be sustainable in the long run, especially considering that it's relying on donations for funding, I believe?

[-] [email protected] 4 points 1 year ago

undefined> metric fuckton of karma farming spam bots.

People are hard at work writing bots for lemmy so don't worry, you'll be able to enjoy your regular hogwash again really soon.

Personally I think lemmy should go as far out of its way as possible to make bots in any and all forms just about impossible.

[-] [email protected] 4 points 1 year ago

Yeah, we can enjoy while it lasts, because with more users more questionable content will come

Thank you very much. The welcome for all us reddit refugees has been really warm and it's deeply appreciated.

[-] [email protected] 11 points 1 year ago

I really appreciate what you're doing, but I'm worried how this instance will continue scaling. What happens when it gets to 1 million users? 10 million? We can scale vertically only somewhat, but horizontal scaling seems to be limited to "just join a new instance 4head" and that just...doesn't have a good experience.

[-] [email protected] 8 points 1 year ago* (last edited 1 year ago)

Ya what are the limitations with scaling horizontally? Scaling up is a stop gap.

Ruud, thank you for your investment here though.

[-] [email protected] 7 points 1 year ago

This server can easily host 1M users.

Most stress on the server comes from all the signups and newcomers posting a lot. After a while that becomes less. On Mastodon, the first days in November I had over 100k active users. Now I have 165k accounts but around 32k active.

And I'm sure the Lemmy devs will also improve the performance of the site. They never really had to, a few days ago the total number of Lemmy users over all instances was 7k.

Performance is looking awesome, lemmy.world is responding very fast to community subscription requests and search is also very fast. My experience when using other instances was that search didn't work at all, hindering community discovery.

Thanks!

[-] [email protected] 6 points 1 year ago

This is how I understand it: a current limitation (feature?) Is that you can only search from your instance to other communities if someone from your instance has interacted with it. But if you use https://browse.feddit.de/ you can search across all instances. Then subscribe to it, or search the whole url in your own instances search. Once an instance interacts with another, now other people from your instance can search for it by simple name.

[-] [email protected] 7 points 1 year ago

Oh, so it is due to the larger userbase here! There is a larger chance that someone already subscribed to a community I am looking for.

Still, when I was using another instance, subscribing to communities at lemmy.world was instantaneous while subbing to communities at beehaw.org or lemmy.ml often took more than one try.

It also doesn't help that lemmy.ml where a lot of users migrated at first seems to be having issues right now.

Also on jerboa searching for communities by url doesn't seem to be working.

Hopefully the influx of new users and attention helps improving and ironing some issues like it happened with mastodon.

So, mostly correct. Lemme clarify:

If you do a URL search in the communities page (with all settings set to "All", even "Communities"), your instance will pull in a few of the latest posts and comments. Not anything too heavy, just enough to give you an idea of what's going on.

The moment a single user on your instance subscribes, your instance will start pulling in everything from that community. If every instance pulled in every community from every other instance, the network would be very vulnerable to a botspam instance that goes up would crash everything. Much better for an instance to only pull in communities that people are interested in.

For less tech-savvy newbies (like me), in case there is some confusion affecting your urge to engage/donate... My friend gave me a great explanation:

  • Lemmy the platform is planet Earth

  • “Instances” like lemmy.world, lemmy.ml, beehaw.org, etc. are like the different countries on Earth

  • When someone signs up, the user picks one instance to be a part of, like how an Earthling becomes a citizen of a country

  • If you register at lemmy.world, that means your home instance/ “home country” is lemmy.world, but you can “travel” to lemmy.ml, another instance / “country”, to check out and subscribe to their community

  • When you subscribe to a different instance that’s not your home instance, you can still participate in their content, and other people will be able to see which instance / “country” you’re from

  • Each instance can have its own version of the same “subreddit”, so you can have a c/Memes in your home instance that is different from a c/Memes in another instance. But you can subscribe to both separately

  • c/[community name] is the naming convention used here I think like r/[subreddit name] on Reddit. If talking about a community in a different instance, it's c/[community name]@[instance name] so like c/[email protected]

  • Donations will help with the cost of running lemmy.world only and not lemmy.ml, beehaw.org, etc.

Someone please correct any of this if any of it is wrong, I’ll happily edit

Hello, i still doesn't quite grasp about the concept of federation and about how fediverse works.

But does it means that one instance can only run from one server?

Say lemmy.world running on Server A lemmy.ml running on Server B

User can register on whichever they want and can see the post from server A and Server B

But when Server A reach maximum capacity, can Server A scale up or distribute the load to multiple instances?

How can we solve the issue of computing power when more and more users migrate to using this services

Thank you 😀

Sorry if its a dumb question, but the whole Federation concept is still new to me. I created multiple account to log in to beehaw, mastodon, lemmy.world, lemmy.ml at first because i dont know that with one user, i can see other communities from another instances

[-] [email protected] 11 points 1 year ago

Optimal would be if users would spread over many servers, instead of all coming to Lemmy.world. But most users don't fully understand the Federation concept so they think they need to register here so they can see local content?

I think the current server can handle a lot of users. It's just the software that isn't ready for it.. but that will improve. If ever this server gets too small, next step would be to scale using Kubernetes, but also that requires the software to be better prepared for that.

I'm trying to figure out why I even saw this post! I've never been to lemmy.world - I'm logged in to (and currently browsing) sh.itjust.works. Not sure why it's showing me this post.

Gonna take a while to wrap my redditor brain around this stuff!

[-] [email protected] 4 points 1 year ago* (last edited 1 year ago)

That's what we mean when we talk about federation!

All the instances are interconnected (unless they block each other). You can post, vote, comment, and even become a moderator of a community on any other instance.

In many ways, it's all one big site. In many ways it's also not, but to the end user who just wants to browse around, it's not as important as people make it out to be.

There's some rough edges around community discovery, cross-instance linking, etc. But the devs are working hard on fixing those issues.

Seems like you've suddenly got a weight to bare. You're clearly lifting it. 👍

[-] [email protected] 5 points 1 year ago

Went ahead and subbed on patreon. Hope that lemmy survives the growing pains and can develop some of the community that reddit had!

Also if there are any fellow former apollo users would def recommend checking out Mlem, its in testflight right now but seems to be working towards the experience that apollo gave on reddit.
