> It's also a lot more expensive. Probably order of magnitude more expensive than the cost of a 1 day outage

Not sure I agree. Yes, network costs are higher, but your overall costs may not be depending on how you architect. Independent services across AZs? Sure. You'll have multiples of your current costs. Deploying your clusters spanning AZs? Not that much - you'll pay for AZ traffic though.

It is when you run your own date centers and have to shell out a large capital outlays to spin up a new datacenter.

The usual way this works (and I assume this is the case for Roblox) is not by constructing buildings, but by renting space in someone else's datacentre.

Pretty much every city worldwide has at least one place providing power, cooling, racks and (optionally) network. You rent space for one or more servers, or you rent racks, or parts of a floor, or whole floors. You buy your own servers, and either install them yourself, or pay the datacentre staff to install them.
