I think this analysis and simulation does not account for one important thing: random routing is stateless and thus easy to be distributed. Routing to the least loaded Dyno needs to be stateful. It is quite easy to implement when you have one centralized router, but for 75 dynos this router would likely become a bottleneck. With many routers, intelligent routing has its own performance cost, the routers need to somehow synchronize state, and the simulation ignores this cost.

> With many routers, intelligent routing has its own performance cost, the routers need to somehow synchronize state, and the simulation ignores this cost. Which is why we pay companies like Heroku to engineer clouds in which to run our applications. Because they're supposed to be better at this than us and spend the time and money building this difficult infrastructure well. That includes a scalable, stateful intelligent routing service.
