Hi there! I'm very glad you liked it! :)

MW does not use any health checks, as it hasn't been migrated to Kubernetes. It's being served by Apache which will be restarted automatically if it crashes. We haven't had any issues with Apache freezing, likely due to stateless nature of PHP and the amount of resources it has available.

I can't speak too much about Chat, as I haven't had much experience with it - I'd have to ask around.

Most of our other services live in Kubernetes, and they're using both readiness and liveness probes, but they're calling the same endpoints of a service.
