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.

Anyone looking to host something big should check out bare metal hosting like Datapacket, Reliablesite, FDCServers, etc. Down side is total lack of handholding and other cloud features and the fact that you can't scale up without redeploying on a new box, but the upside is ridiculously cheap bandwidth. The bandwidth cost is by size of pipe, not gigabyte transferred, and pipes upwards of 10gbps are affordable.

OVH and Hetzner are also worth looking at but aren't quite as cheap bandwidth-wise.

Performance is looking awesome, lemmy.world is responding very fast to community subscription requests and search is also very fast. My experience when using other instances was that search didn't work at all, hindering community discovery.

Thanks!

I'm not too familiar with Lemmy's codebase, but I am a devops engineer. Is the software written in any way to support horizontal scaling? If so, I'd be happy to consult/help to get the instance onto an autoscaling platform eventually.

Doesnโ€™t support HA or horizontal scaling yet from what I read. Unsure if kbin does. Probably would have to add support for horizontal scaling to have that auto scaling do anything.

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 ๐Ÿ˜€

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
