My guess is that CF has so many external customers that they need to move fast and try not to break things. My hunch is that their culture always favors moving fast. As long as they are not breaking too many things, customers won't leave them.

There is nothing wrong with moving fast and deploying fast.

I'm more talking about how slow it was to detect the issue caused by the config change, and perform the rollback of the config change. It took 20 minutes.
