What hardware does lemmy world use?

I'm just curious how sustainable the whole lemmy operation is.

I found this post: https://lemmy.world/post/75556

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.

Though this was 3 years ago. I don't know if they changed the server or not since then.

It is also very important to note that this is not only used for lemmy.world, but also mastodon.world. And by now, it probably is also used for other services the Fedihosting foundation hosts: https://fedihosting.foundation/

edit: incorrect info, see MrKaplan's comment under this one

You can see the expenses here: https://opencollective.com/mastodonworld/transactions?kind=EXPENSE

Single user instances are fairly cheap to run though, if you are interested in that. I've been running this instance on a cheap Hetzner VPS for about 1.5 years and haven't experienced any major problems since.

Oh that's helpful. Yeah makes sense they use hetzner as it's pretty good value for what you get.
I guess I would be shocked it's a single server but also impressive if true

I don’t know if they changed the server

it's still the same one.

this is not only used for lemmy.world, but also mastodon.world

this is not correct - they have the same specs i believe, but it's 2 separate servers.

by now, it probably is also used for other services the Fedihosting foundation hosts

that is also not correct. pretty much all our services are isolated on VM or physical box level currently, although we are looking into a potential migration to kubernetes to use our hardware resource more efficiently, as we have a lot of unused resources with our current setup due to downscaling being a bit challenging with hardware and with the current market in general. lemmy.world and mastodon.world run on baremetal, most other services on hetzner cloud VMs.

It's not, see other comment in the thread

Thank you for the correction. I didn't know that and just made an assumption. I'll correct my comment now.
