alt Hacker NewsI think you are giving them way too much leeway. For the service they provide there’s no technical reason it can’t be infinitely scalable. For example their “pull request” page constantly goes down. Serving that kind of workload at high burst load is a fully solved problem.
If they are genuinely compute constrained on CI they should obviously reduce the free offerings rather than take down all their paying customers constantly.
You are basically saying that you, from the outside, have solved the problem perfectly and the whole team of engineers at GitHub just don't know about this one simple solution you are proposing.
Have you considered that you don't have the full context of the problem and it's not "just" a few small tweaks?
