MS need to dogfood their own product. They should be rolling out the updates across their entire infrastructure before letting them loose on the wider world. Imagine the s**t storm if Nadella walked into the dev team's building and said: "The latest update just deleted all my data"
I heard a story about an email server product (now sadly passed away). The users kept on complaining that when they did certain maintenance tasks, the mailstore would get corrupted. In the end the product manager made the maintenance tasks run on the devs mailboxes every few days. The reliability went through the roof.
