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.

Doesn't solve the availability issues, though. I know of no seriously hosted system that doesn't have at least two replicas in different availability zones. I don't expect any hobby instance to offer any kind of availability guarantee. But if we want to have one or two central instances that the typical reddit user can flock to, this would IMO be essential to have.

Also, in my experience it is FAR cheaper to have a few low to mid range systems for vertical scaling, than to throw a high end machine at it for vertical scaling. If you look the the pricing, the monthly costs for vertical scaling goes up exponentially once you want much more RAM and CPU cores (and storage, and so on).

Being able to scale horizontally solves both issues: hardware is cheaper and reliability is higher.

That lemmy is so damn efficient would then simply mean, that we can achieve excessively good results with low resources, where Reddit would already struggly and needs to put much more machines in place. That would be a nice "business" advantage.
