[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.

What's the current setup, if you don't mind me asking?

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

Done and done. Thank you for your great support of the community!

My submissions still hang indefinitely, but when I reload they are there. I dunno if this is something connected to lemmy's code itself or the server but it's a bit broken

I think some donation flare would be cool to have if you make a donation to an instance. It would help incentivize donations too.

Thanks for you work on this! What is the planned time for the outage?

Does it work on water now that it has MORE POWA?

I just hope this doesn't cause ossies down the line. A lot of us are from reddit, and it wouldn't shock me if a lot of new users go back to reddit regardless of the outcome.

I'd hate for this situation to put unessecary financial strain on this service

OpenCollective link gives me "Unexpected error". Edit: got it now

What is the service consumming most resources? Postgres, backend, frotend, nginx, pics?

@ruud Wow! 12k users since 1st of June , so in 12 days? That's pretty impressive!

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

Thank you. Feels super responsive.

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

@ruud I hope it all works well, how can I support the server?

[–] [email protected] 1 points 1 year ago (2 children)

What is the ratio from the before and after migration server capacity? 1:3, maybe 1:5?
