One thing that caught my eye in the Spotify screenshot is that there's what is presumably a Python 2 -> Python 3 migration monitor, which is also the only red one. I would typically assume that a code migration would be much more difficult than a data migration, which sort of feeds into that "Python would be the only red migration monitor" idea, even if data migrations are more complex from a making-sure-everything-works perspective.
