It would be nice to have HA requirements written down. Mayo used to say that 15-20 min failover during a region failure would be fine, but that was before FxA was intended to support the world.

I encourage others to weigh in here. Left to my own devices, I'd lean to taking on more HA risk in the beginning in favor keeping things simple and nimble. I want to aggressively avoid Rube Goldberg complexity foot guns before we even have any users.
