Because we needed geographic distribution so that we don't end up hairpinning our users, and they only run a single service so the value prop is much lower. We use route 53 to do geodns across a number of cheap instances around the world (which is also nice, let's you pick regions with cheap bandwidth but good latency to major metro areas). We currently have TURN relays in Las Vegas, New York, and Amsterdam and that gives us pretty good coverage (sorry Asia...you're just so damn expensive!).

But all of our APIs sit in one k8s cluster across two datacenters (Hetzner, with whom we couldn't be happier).
