[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.

For less tech-savvy newbies (like me), in case there is some confusion affecting your urge to engage/donate... My friend gave me a great explanation:

Lemmy the platform is planet Earth
“Instances” like lemmy.world, lemmy.ml, beehaw.org, etc. are like the different countries on Earth
When someone signs up, the user picks one instance to be a part of, like how an Earthling becomes a citizen of a country
If you register at lemmy.world, that means your home instance/ “home country” is lemmy.world, but you can “travel” to lemmy.ml, another instance / “country”, to check out and subscribe to their community
When you subscribe to a different instance that’s not your home instance, you can still participate in their content, and other people will be able to see which instance / “country” you’re from
Each instance can have its own version of the same “subreddit”, so you can have a c/Memes in your home instance that is different from a c/Memes in another instance. But you can subscribe to both separately
c/[community name] is the naming convention used here I think like r/[subreddit name] on Reddit. If talking about a community in a different instance, it's c/[community name]@[instance name] so like c/[email protected]
Donations will help with the cost of running lemmy.world only and not lemmy.ml, beehaw.org, etc.

Someone please correct any of this if any of it is wrong, I’ll happily edit

Is there a way to view C/Memes in all instances at once in aggregate? I don't want to miss out on what other instances are doing.

Not yet, although there is ongoing discussion about this

I'm new here so I might not be asking the right question. As I understand it there are many subforums one on each instance with the same exact name. Are they all shown at once while browsing? Can they be?

I wasn't talking about multiforums but that's good to know too.

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

There can be multiple communities with the same name, that doesn't mean there are. Like how [email protected] and [email protected] are the same "name" but a different domain.

So say for example you and your friend start up your own Lemmy instance and decide to make your own community called "Funny" where you can post jokes, without bothering to check if there was already a more popular "Funny" in someone else's instance. There's nothing stopping you and now there will be two communities called Funny, but one would be [email protected] and yours would be [email protected]

If your "Funny" gets to be really popular too, then other people might choose to subscribe to both Funny communities, and then posts from both would be in their feed. However they are distinctly seperate and you will continue to own and run yours and lemmy.world would own theirs.

Does that make sense? I know it's a weird concept when you're used to unique names in Reddit, but it's not all that different from r/news and r/worldnews covering similar content but controlled by different people.
