[Done] Server will be migrated (More power!) (lemmy.world)

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 @veroxii@lemmy.world for assisting with that.

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.

Perhaps having the lemmy main site suggest servers with less load in a dynamic way would help with this. Instance xyz is now recommended on the main page due to having less users. The main problem I see with that is that there are different "themed" and what is suggested may not match up with the user's preferences and tastes.

Thanks for setting up and managing the instances.

This is already the case I think. But the server must meet certain requirements, including specifically opting into being recommended.

Hello, after reading all the comments, I realized that I share the same questions (sort of) with the others.

Thank you for replying and clarify things

Cheers Ruud. And thank you ๐Ÿ˜Š

You're seeing mostly CPU bottlenecks I assume?

What's your RAM and storage situation looking like?

It does matter where you call home though because beehaw just defederated and there was quite a lot of good content there.
