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.

Thank you very much! πŸ₯³

I don't understand why a dedicated server is a good idea, when the only true way to scale is to use like Kubernetes or Docker and ECS Containers with scale?

Your just gonna run into more problems, you cannot vertically scale forever.

Just joined. Thank you so much for your effort!

More power! More power is good.

@[email protected] DM me if you need help setting up monitoring/alerting on server health. IRL I'm on an SRE team, so happy to help where I can!

Just curious, what sort of hardware is lemmy.world using/moving to? Wondering if there's a good way to predict load based on number of users.

What's the operating cost? Thank you, for running this server! :)

Are you running this out of your home?

I have self hosted small things before, but I was always curious about lager stuff like this.

What are your internet speeds?

Check the updated post. It's running on a dedicated server hosted by Hetzner. Specs are high-end: "AMD EPYC 7502P 32 Cores β€œRome” CPU and 128GB RAM."

[–] [email protected] 0 points 1 year ago (1 children)

Thanks for letting me know. I also have my work stuff on Hetzner. But I do not see "Hetzner" listed in this post.

Have you ever hosted on Vultr? I need a server with less latency and Vultr seems to have servers in a good location for my needs.

[–] [email protected] 1 points 1 year ago

Ah you're right. The post only states the specs. The fact that it's hosted on Hetzner was mentioned in a comment (1, 2)

I personally have no experience with Vultr. Sorry!

[–] [email protected] 0 points 1 year ago (1 children)

12k ??? That's crazy! It was only 500 when I joined 6 days ago, wow!

No worries for the downtime, when it's needed, it's needed :)

[–] [email protected] 0 points 1 year ago (1 children)

probably mostly due to the reddit situation. at least thats why im here now

I'm not sure how its being done as far as the technical aspects but Ruud has done a great job as admin upgrading the servers to keep up and anticipating the flow of new users.

The same admin also has experience with a mastadon.world server that experienced lots of growth from Twitter users leaving over musk moves. So essentially we have a good admin as far as I can tell and it's not his first rodeo. Part of the reason I chose this server

Anyone looking to host something big should check out bare metal hosting like Datapacket, Reliablesite, FDCServers, etc. Down side is total lack of handholding and other cloud features and the fact that you can't scale up without redeploying on a new box, but the upside is ridiculously cheap bandwidth. The bandwidth cost is by size of pipe, not gigabyte transferred, and pipes upwards of 10gbps are affordable.

OVH and Hetzner are also worth looking at but aren't quite as cheap bandwidth-wise.

Would be awesome if you create some group chat (e.g. Discord?) and add sysadmins/devops to it. Would be more than happy to assist, especially if you have questions or need opinions.

I've been working as sre/sysadmin/devops for the past ~5 years and ~9 years of (Arch) Linux user. More than 1K Arch Wiki edits over that period of time.
