[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 @[email protected] for assisting with that.

This is literally a Wikipedia moment for social media, thank you @Ruud

Is one donation method preferred over another? That is to say, is one cheaper than the other?

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

Incredible. Thank you for your efforts on this!

So, I just want to make sure I understand this as I am a new user from reddit. Instances are server based and cost money. Instances are Lemmy.World, Beebaw, Lemmy.Film, etc etc. These are all seperate hosted instances. Correct?

And donations would help pay for the server, ie lemmy.world?

[–] [email protected] 2 points 1 year ago

Yes, lemmy.world, lemmy.film, beebaw and etc are other instances of Lemmy and users from other instances can interact with other instances.

And yes donations help the server afloat.

Pretty cool stuff.

"Lemmy instances" are analogous to "email servers": your account is hosted on one of them, but you can communicate with people on other ones, because the servers know how to talk to each other.

Expanding the capacity of the Lemmy service will involve both (1) more instances, and (2) more resources for existing instances.

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?

[–] [email protected] 2 points 1 year ago (1 children)

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

[–] [email protected] 2 points 1 year ago (2 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] 2 points 1 year ago* (last edited 1 year ago)

Actually just had a short conversation with @[email protected] about the latency. We're going to try and address that for those of us outside of Europe.

[–] [email protected] 2 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] 2 points 1 year ago

Does it work on water now that it has MORE POWA?

[–] [email protected] 2 points 1 year ago

What kind of server configuration are you guys running? A single instance?

[–] [email protected] 2 points 1 year ago

Thank you. Feels super responsive.

[–] [email protected] 2 points 1 year ago (6 children)

I'm not too familiar with Lemmy's codebase, but I am a devops engineer. Is the software written in any way to support horizontal scaling? If so, I'd be happy to consult/help to get the instance onto an autoscaling platform eventually.
