A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.
Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

So there is no way to horizontally scale?
The network can actually scale quite well thanks to the fact that other instances will act as mirrors of communities!
But what happens when the instance hosting the community goes down? Are all external instances still able to participate in that community? I get that they are mirrored but will everyone still be connected?
No. The "single source of truth" is the instance hosting the community. If it goes down the community itself goes down with the ship. The only way to prevent it is to have a IT infrastructure that can provide redundancy
Yeah, that isn't good.
having a redundant system is feasible (I'm just a dev, not an architect so don't take my words for granted) but it have to be designed and putted together ... and prices are gonna skyrocket
Lemmy / the fediverse isn't designed this way, but it could be. There are certainly systems that share diskspace and are multimaster and keep stuff as long as someone is interested in it(i.e. accessing the data). I really start to think added to the lemmy / fediverse servers should be something like what freenet used to do in terms of hosting content.
If it's just a temporary outage, whatever the mirror has received prior to the outage will be shown to users on that other instance but only local interactions for that instance will update it, when it comes back up, things like votes and comments will be synchronized again across all of the instances.
For permanent outages, the community will just need to be started again on a new instance.
But they could pick up where the now defunct community left off, right? Like, the cached copy from another server could be imported on a new server elsewhere?
That functionality doesn't currently exist, but migration of communities is something that's being actively talked about for development.
Reading this and trying to visualize the big picture, I think this is where kbin's magazine is going to win out in the end
Out of curiosity, how is kbin's magazine system designed to avoid this problem?
From what I understand... wait I understand nothing
Ok, from what I understand now, a magazine can follow tags or keywords, which will populate the magazine. So no matter where in the fediverse something is posted, it will show up in the magazine.
But then if the instance hosting the magazine goes down YEAH OK I GET IT NOW
It’s not
