    A payments and ride-hailing platform of Grab's shape replaced its weekly change advisory board with automated gates fourteen months ago. At 23:40 a configuration change reaches production through the emergency path and skips the canary stage. By 23:46 card authorisations are failing in two markets; recovery takes 51 minutes. The review finds that 38% of production changes in the previous quarter used the emergency path, median approval 90 seconds by whoever was on call. What failed?

    Reddit's 14 March 2023 outage ran 314 minutes after a Kubernetes 1.23 to 1.24 upgrade removed the node-role.kubernetes.io/master label that Calico route reflector selectors depended on, and Kubernetes has no supported downgrade. Sequence the next cluster upgrade so a gate can actually block it.
