What would happen if instead of users swarming existing servers when a fediverse service was put in the spotlight, each user spun up their own micro-instance and tried to federate with existing servers?
There’s always the odd person who decides to host a personal fediverse service in their homelab for themselves, but would the fediverse work if that was actually the primary mode of interaction? Or would it fail in a similar way to now where the servers which receive the most federation requests need to scale up?
Presumably the failure modes for federation are easier to scale than browser requests since it’s an async process.
So let’s say we want to scale up to several million users - what would that look like?
Well, if we wanted say 50 million users at 4000 users per instance we would have 10000 instances. If we wanted 1 billion users we would have 200 thousand instances
