[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 @veroxii@lemmy.world for assisting with that.

More power! More power is good.

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

"All good!"

[–] Saturdaycat@reddthat.com 6 points 2 years ago

That's awesome! Wasn't even a long downtime

[–] delaghetto@lemmy.world 6 points 2 years ago (5 children)

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?

How to contribute? Do you have Patreon?

Hello, i still doesn't quite grasp about the concept of federation and about how fediverse works.

But does it means that one instance can only run from one server?

Say lemmy.world running on Server A lemmy.ml running on Server B

User can register on whichever they want and can see the post from server A and Server B

But when Server A reach maximum capacity, can Server A scale up or distribute the load to multiple instances?

How can we solve the issue of computing power when more and more users migrate to using this services

Thank you 😀

Sorry if its a dumb question, but the whole Federation concept is still new to me. I created multiple account to log in to beehaw, mastodon, lemmy.world, lemmy.ml at first because i dont know that with one user, i can see other communities from another instances

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.

[–] OneShoeBoy@lemmy.world 6 points 2 years ago

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

Seems like you've suddenly got a weight to bare. You're clearly lifting it. 👍

[–] kiyoomii@lemmy.world 5 points 2 years ago

Incredible. Thank you for your efforts on this!

[–] ShadowCatEXE@lemmy.world 5 points 2 years ago (5 children)

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

[–] ericjmorey@beehaw.org 7 points 2 years ago (1 children)

The cheapest configuration for that server on Hetzner is about €150 per month.

[–] ShadowCatEXE@lemmy.world 9 points 2 years ago

Honestly cheaper than I would have expected. However, still a nice chunk of money to shell out for a community, and for that, I commend.

That's my admin!

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?

[–] savjee@lemmy.world 8 points 2 years 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."

[–] worfamerryman@beehaw.org 6 points 2 years 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.

do you plan to publish any of your scaling data? Some others might consider helping by running large instances and your learnings would be incredibly helpful.
