I watch Mayday with interest not simply because I like airplanes so much but because the investigation of why aircraft crash (and why so few of them do) teaches me a lot about how we know what we know. This article isn't about airplane crashes, it's about site reliability, but many of the conclusions are the same, for example, about why there's rarely a 'root cause' for any event, about why 'human error' is rarely the cause of any crash, and about how complex systems are, well, complex, which means there are elements of them that elude understanding entirely. As Michael Stiefel says in this interview, it's like "Rilke's famous expression, 'Living the question', because an architecture is never done. You never should think of it as done."
