2707 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

In July 2024 a CrowdStrike content update - not a sensor code release - caused Windows hosts to crash worldwide, with Microsoft estimating about 8.5 million affected devices. The sensor software itself had been through staged release. What does this teach about artefact management, and where would over-correcting be a mistake?
