What Was the Problem With the OS Upgrade?

The problem was, you could say, both technical but organization and Conway's Law today mirror each other. It was a technical problem tied to the OS upgrade but an organizational problem because the pain of the ops team in terms of deploying was not at all felt by the dev team as they were just incentivized to release. That is really interesting. Curious for the team that was having difficulty with delivery and you mentioned their deployments and lead time were maybe a little bit alarming. What were the actual problems contributing to that?
