This site is currently struggling to handle the amount of new users. I have already upgraded the server, but it will go down regardless if half of Reddit tries to join.
However Lemmy is federated software, meaning you can interact seamlessly with communities on other instances like beehaw.org or lemmy.one. The documentation explains in more detail how this works. Use the instance list to find one where you can register. Then use the Community Browser to find interesting communities. Paste the community url into the search field to follow it.
You can help other Reddit refugees by inviting them to the same Lemmy instance where you joined. This way we can spread the load across many different servers. And users with similar interests will end up together on the same instances. Others on the same instance can also automatically see posts from all the communities that you follow.
Edit: If you moderate a large subreddit, do not link your users directly to lemmy.ml in your announcements. That way the server will only go down sooner.
You must log in or register to comment.
I’m going to set up a general purpose instance tomorrow with the intention of handling a relatively large number of users. The main problem is choosing a domain!
Naming things is one of the two most difficult issues in IT, alongside cache validation and off-by-one errors.
I was also contemplating setting up a new instance for this. I have 100s of gigs of unused ram, CPUs on idle and a 10gbit connection looking for something to do. The only issue I couldn’t figure out was the name. I own itjust.works was thinking of something clever subdomain to use with it. I’m glad I’m not the only one with this issue
YetAnotherLemmy.Social coming online now soon?
It’s a week later, but I did get this done finally. I’ve set up https://lem.monster/ . Still doing some tweaking, but it’s open.
Lemmy.world is a new server, accepting signups. You’re welcome there.
Sadly, I feel like the Fediverse, based on ActivityPub, was fundamentally designed wrong for scaling potential. I do like Fedi and I like ActivityPub, but I think instances should not have to be responsible for all of this:
- Owning user accounts
- Exclusively host communities
- Serving local and remote users webpages and media
- Never going down, as this results in users and content becoming unavailable
Because servers “own” the user accounts and communities it’s not trivial for users to switch to a different instance, and as instances scale their costs go up slightly exponentially.
I wish the Fediverse from the beginning was a truly distributed content replication platform, usenet-style or Matrix-style, and every instance would add additional capacity to the network instead of hosting specific communities or users.
I guess it’s a bit too late for a redesign now… Perhaps decentralized identifiers will take us there in some form in the future.
Not sure why you reference Matrix, which has even worse scaling issues as it indeed tries to replicate nearly the entire network on every server.
The Fediverse is really just working how the general web does, just with some standardized API for websites to interact. It’s not perfect, but it works and has proven to be relatively scalable.
It sounds a bit like you had a bit too much of the Bluesky cool-aid, which indeed replicates nearly all of the mistakes of Matrix and makes it impossible to scale via small community owned servers instead of big company owned data-centers (which might be by design?).
Well yeah, point taken that replicating everything everywhere and forever might be impossible. But I do believe at a minimum my identity should be portable and accessing Fedi (ie. in microblogging: posting and viewing a feed of the latest posts of my follows) should be decoupled from which instance I pick to access the Fediverse.
I don’t particularly like how owners of instances which grew are now essentially locked in to having to spend 100s or 1000s of dollars a month keeping their now expensive instances running and providing service. This is a bad place to be for a platform ran by volunteers. Letting instance owners scale their service down as well as up would be ideal. But this requires at least decentralized identity, and at best some form of content hosting redundancy…
It’s easy to say the current architecture of Fedi works when it’s still small. Your instance has 139 users… That’s not intended as a slight. Hosting instances is good and I applaud you for it! But I wish it were easier to more equally share the load once the platform becomes more popular.
Is there any group of devs that work on this issue that you know of? I’d be interested in looking into it.
No. And I think it’s a really hard problem. poVoq was right to call me out on full replication being a bad move, because duplicating all content on every server is obviously inefficient. But a solution in-between, with decentralization and redundancy, is probably a very complex challenge. Doesn’t seem impossible, but very complex network protocols rarely seem to succeed.
Edit: Sorry I was still thinking about some fabled perfect protocol. But if you’re looking into decentralized identifiers, W3 is working on one approach. It’s not something I have seen used anywhere or integrated with ActivityPub yet, but that could be the future I’m hoping for. Probably.
It almost sounds like you’re describing RAID 5 of content across fediverse servers.
Something like that. But also with fully decentralized identity. So all content is signed by a keypair which is local to the user, and can be used to access Fedi through arbitrary instances. Probably I am too wishful.
I like the idea of decentralizing identity. One of the oddest things about the current fediverse is how closely tied accounts are to servers that host specific content. From the server’s perspective it would be like everything’s posted anonymously except all the messages are pgp signed.
But how would the system handle user customization settings? Things like blocked users or subscribed topics. Would that all need to be stored locally in your browser and parsed by the arbitrary instance you’re using?
And what if some instances want to refuse hosting certain content on the network. Maybe there’s some way defederating instances could account for that.
I could envision a 2nd class of server, running something like OAuth/OIDC, which handles the authentication into any Lemmy instance (or better yet, any ActivityPub based instance).
This server would also be self-hostable, and provide only authentication services, so it would be rather lightweight. But would help reduce the load on the content servers.
I feel like for decentralized identity maybe a page could be taken out of Blockchain. Ethereum ledger is duplicated in its entirety on every host, and there are L2s that help spread the load but roll up to the L1. If identity could be attached to something like that, each person has a key to identify themselves. Identity I think would be best separated from all content related to the identity, the user could choose a server to host that data, as well as back it up with like a shared user data backup agreement between a few servers in case one dies. It’d be very similar to raid but the data only needs to be on 2-3 servers. I suppose community data could be the same. I can envision when a new server joins the federation, it could be auto assigned to share with 2-3 similarly sized communities with algorithms making sure there aren’t any closed groups of sharing (a->b&c, b->a&c, c->a&b) wouldn’t ever want that. They all seems to be the most reasonable solution in my head.
Yeah, the fact that the user auth and permission models were intentionally left out of the W3C spec initially really ended up locking ActivityPub into particular dialects and patterns that are now proving problematic for scaling.
I’m not sure it’s 100% too late for a redesign, though. The committee is still active and the Fediverse could still theoretically grow by an order of magnitude or two. Does that seem likely right this minute? No, but sometimes that kind of vision is what an ecosystem needs.
Thank you for posting this, as you seem to have more knowledge of the underlying protocols than i have. Had some visions of server takedowns and meltdowns. I have little idea how the protocol works but i’d imagine that account migration/replication would not be such a big deal to implement, and communities are already being replicated, no? As a work-around.
While it might not be too late for that update, it would require some reconciliation to happen. There’s the potential for multiple users and communities of the same name across servers that would need to be considered.
Following a decentralized identifier would essentially be like following a unique public key. Their screen name is just some text which can be anything. The bigger problem is the overall infrastructure of Fedi which is very much based on lists of user@domain … this no longer trivially works if the “user” you follow could be posting from anywhere. It doesn’t seem unsolvable, just kind of difficult to imagine with the momentum behind Fedi as it is right now.
I think lemmy will be bitten in the ass by not having considered clustering/horizontal scaling from the start. Federation alone as a scaling mechanism is only feasible for “nerds”. But if the network wants to grow, we will need a few scale-able large hosted instances. And if their only choice is to scale vertically, there will be a hard limit (unless we put a good old Mainframe somewhere ^^).
Another downside of this design is: you can’t run it with high availability. If there’s only one process per instance, updating it will mean the whole instance is down. Sure, if all goes well this downtime is under a second. But if it doesn’t go well or if a migration is needed, this might quickly become hours.
Over at https://join-lemmy.org/ , when someone clicked on “Join a Server”, they are presented with a list of instances, it’s not that obvious that these are cross-accessible (yes, the homepage mentioned it, but not here), and people are bound to look for one with the most users.
Perhaps, add a simple TLI5 explanation/diagram explaining how Lemmy works on https://join-lemmy.org/instances .
(The documents are also too wordy for most people to care.)
Pull requests welcome, the code is here: https://github.com/LemmyNet/joinlemmy-site
@nutomic@lemmy.ml It might be a good idea to default the Communities page to All instead of Local, to help push users into discovering other instances and promote them.
Point us to where the coin slot is. E.g. Patreon. We insert coin 🪙, you upgrade.
I tried like 4 or 5 instances before coming to lemmy.ml, but none of them were taking applications anymore. Finding even those was a hassle, since all I got was a list of domains without any details as to what the instance is about or if they allowed newcomers.
Now that I’ve setup everything, Lemmy does seem like nice alternative to Reddit, but as someone from the outside, all of this is daunting.
I have been wondering how cumbersome the Lemmy design will become for some. I love the idea that it is federated and decentralized however these are also major drawbacks for most
averageusers (i.e not multi account users.Multiple accounts needed for
maximum uptimeon different instances. What if I really like my username and its taken on another instance? If one instance is down and i comment with my other account will i then need to manage replies etc through different profiles? What happens if something spins up another instance of a similar domain so that they can get a username of someone to imitate them? I am sure these can be blocked after the fact or will other federated instances be automatically blocked.What happens when someone gets bored of their instance and stops it, or it gets blocked, or they start getting unwanted attention. Does this mean all that content then goes into the ether?
Will this go down the route of whomever provides the instance with the most resources, best load balancing becoming
the one, blocking other instances and controlling it as if it were private and independent?There are a lot
wait and seethings, but I am excited to help and see what this great project becomes.Another thing:
We do need more site admins to help us handle the applications and moderation.
For obvious reasons, we prefer ppl who have been here for a long time, and post / comment consistently. If you’d like to help us out, so that nutomic and I can focus on coding, that would be splendid.
I sent my registration yesterday, because I signed in another instance, one from my country, but I couldn’t see all the post and no comments from lemmy.ml even thought is supposedly linked, so thank you for approving my account.
Even if I’m a tech savvy person I found the whole experience of joining lemmy pretty bad, I like the concept of federation, but I think it’s too confusing to normal people, it really needs to be more seamless if you want to grow, how? idk, I was thinking some sort of replication, when you sign up, you are registered to the main instance (this) and given the choice to select other instances, automatically selecting let’s say another 3 based on your location, then your account is synced in all the registered and linked instances, when you login if an instance is experiencing overload then it switches to another one. I don’t know if this is realistic or out of the scope of Lemmy, or maybe against the philosophy of it. I’m just rambling.
I’m just glad that there is an open alternative for anonymous social interaction in this day of walled internet services such as discord, twitter, facebook etc. and I wish you all the success.
If now is struggling then on June 12 will be a nightmare.
Reddit will go dark in protest, many messages to join Lemmy, most instances will be overloaded or even DDoS with so many users, like what happen with Mastodon.I just created https://lemmy.studio/ for music-related discussions.
Is there any way to migrate instance or do I make a new account entirely?
Users are likely going to see this as it’s the “official” Lemmy instance when trying to join for the first time.
Any admins of instances that are accepting people, give your best elevator pitch!
