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.

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 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.

Always give a long estimate so people are pleasantly surprised :)

I’m just another reddit refugee but I wanted to say thank you for your time, effort and money. As I slowly come to terms with federation I see why some are so passionate about it.

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.

Wouldn't something like a Matrix server be more in line with the 'philosophy' of the fediverse?

Reddit is for Lemmy as Discord is for Spacebar (works with Discord) https://github.com/spacebarchat/spacebarchat

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

I’m glad to hear about the new users (I myself am one.) and the server upgrades!

I think lemmy.world suits me better than Beehaw. (great folks over there, no shade)

I like that lemmy.world let’s communities be openly created by users, as well as the inclusion of downvoting which I personally prefer.
