High realiabity and high availability are not the same thing though. There are still problems in aviation, like the dreamliner who had to be restarted every x days or it would go full system shutdown. In these kind of systems you often sacrifice availability for reliability. You also sacrifice progress for reliability, which is absolutely the right thing to do for these projects. An on call engineer shouldn't be the solution for bad reliability, because as you said it doesn't help. He is primarily there for availability. Instead of high throughput I maybe should've said highly available systems.
