    But what happens when the instance hosting the community goes down? Are all external instances still able to participate in that community?

      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

          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

      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
