    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

          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.
