@luke Thanks for shedding some light on how the builds are working.I’ve seeing many users complaining about this. This is a real problem.
One common question i’m seeing in netlify/community - Gitter is about System resources: How many RAM and CPU is available during build?
To be honest i taught build times are set to 30 mins before, because we were seeing timeouts after 30 mins, it could be just an illusion.
One solution might to have a more finer grained pricing solution between the starter and the pro where we can buy build time resources. The Pro tier is really about Team collaboration which makes sense, enabling 3 concurrent builds makes sense, but does the build resources are bigger in the PRO tier?
