Istio, we have a problem! Understanding and fixing bugs with a service-mesh
summary
Istio is used to add L7 visibility and control to a Kubernetes quiz app deployed via scaffold; the service graph and Prometheus/Grafana dashboards show one path failing about 50% failure while a patched version returns 100% success. Traces reveal an endpoint choosing the same hexagon repeatedly, code is rebuilt and deployed, and Istio routes traffic with traffic mirroring and a progressive canary so the fix is validated under production load before switching users.
