[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.

I'm trying to figure out why I even saw this post! I've never been to lemmy.world - I'm logged in to (and currently browsing) sh.itjust.works. Not sure why it's showing me this post.

Gonna take a while to wrap my redditor brain around this stuff!

That's what we mean when we talk about federation!

All the instances are interconnected (unless they block each other). You can post, vote, comment, and even become a moderator of a community on any other instance.

In many ways, it's all one big site. In many ways it's also not, but to the end user who just wants to browse around, it's not as important as people make it out to be.

There's some rough edges around community discovery, cross-instance linking, etc. But the devs are working hard on fixing those issues.

I understood that I would see remote (is that the right word?) communities to which I had subscribed. Am I also seeing communities to which my local users have subscribed? I don't think I'd want that.

There's a few tabs at the top of the feed (on the site, apps might be different)

"Local" shows all content from communities on your instance.

"All" shows content from all communities on all instances that your instance has "discovered". Your instance will discover a remote community once at least one member of your instance searches for it and subscribes.

"Subscribed" shows content from communities you've subscribed to, both local and remote.

Thank you! That's tremendously helpful.
