And if you have restarts without downtime, there is no need for configuration reloads anymore. Why solve the same problem in 2 ways? It would just increase a chance for bugs.
All in all, HAproxy is a brilliant piece of software and Willy is running it in an exemplary way. Kudos!

That's a good point, I must have skimmed that part.
"Service upgrades are even more important because, while some products are designed from the ground to support config updates without having to be reloaded, they cannot be upgraded at all without a stop/start sequence. Consequently, admins leave bogus versions of those software components running in production because it is never the right time to do it."
