What happens if the instance which hosts the community is down but other instances are online? I just made a post to a community on an instance that doesn’t exist anymore, but will other instances get that post, or is it reliant on the instance which hosts the community coming back online?

That post will only exist on your instance. Federation out to other instances would have to happen via the instance that community is on.

You may think of the community as down in that case, but overall the service is more resilient than a single community.

To be fair though, the chance that every Lemmy instance goes down at the same time is so much lower than Reddit going down. Sure, my instance might be unavailable, but I'd be able to hop onto the next one and continue.

Considering the distributed nature of the fediverse, the only way I could imagine the entire thing going down is either a botched update that everyone somehow manages to install at once, or a very sophisticated distributed attack.

The latter would be the most realistic as someone could find a way to poison the ActivityPub protocol or there’s a bug in it and then a message would go to all servers simultaneously.

I was just thinking this should be a "First time?" meme instead. It feels like there's always one instance down.

But it's nice that Lemmy as a whole is never down, just individual pieces.

Every time one instance is down, I switch to another. I've never seen it down completely.

...you were saying?

my experience is a bit different. when the instance with your account and subscribed channels is down, it's just not a good experience

!? Future feature request for Lemmies : Backup and restore subscriptions to hop fast to another instance in case of downtime.

Sync has this

Unless every instance goes down we will just call it a partial outage.

I think lemmy.world beats reddit. And it's one of the worst offenders.
