[Done] Server will be migrated (More power!) (self.lemmyworld)

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 happens if millions of users migrate over?

There are multiple instances, so people could theoretically be blocked from adding an account on this instance and be required to create an account on another instance. Since it's federated and everyone has access to everything on other servers, it shouldn't be a problem.

Given that every instance sees content from all the others, won't the cost per instance grow with the total number of users? If there are 500M global lemmy users, how much would it cost to run a "small" instance to process that firehose of data?

A server would die and millions of users will lurk for another Reddit clone to settle
