LINUX-1233Tar extraction preserves paths but the deploy still breaksA deployment archive extracts successfully, but later cleanup or symlink logic targets an unexpected parent directory.LinuxIntermediate15 minPro LINUX-1265A reverse proxy only breaks WebSocket auth flowsLinux incident scenario used for structured troubleshooting practice.LinuxIntermediate16 minPro LINUX-1270A reverse proxy only breaks WebSocket auth flowsAn authentication layer added at the reverse proxy works for ordinary pages and suddenly breaks upgraded connections or live UI channels.LinuxIntermediate16 minPro LINUX-1228The cron job succeeds interactively but fails overnightA maintenance script works during manual testing and later breaks only when cron runs it unattended.LinuxIntermediate16 minPro LINUX-1196Systemd timer runs but the wrapped script sees a different working directory than the shell versionA maintenance job appears healthy under manual testing, yet fails under the timer because the script expects relative paths from a different working directory.LinuxIntermediate17 minPro CICD-387A canary job compares median latency while one percentile tail explodes only for a tenant class routed through a different auth provider during a staged decommissionAggregate health stays green while a routed subset proves the release is unsafe. The service still works through the primary path, but one dependency only fails when the old component is finally drained away.CI/CDAdvanced18 minPro K8S-210A cluster-wide mutation helps services and breaks a workload class with different lifecycle semantics during a failover rehearsalThe platform-level change is broadly useful while one specialized workload class cannot honor its assumptions. Normal traffic masked the issue until the standby or alternate path became active under rehearsal conditions.KubernetesAdvanced18 minPro K8S-156An externalSecrets controller refreshes the Secret, but the mounted CSI volume caches the previous version and the app sees mixed credentialsSecret state is updated centrally, yet different delivery paths serve different generations at runtime.KubernetesAdvanced18 minPro SECURITY-023API key restriction by source IP breaks autoscaled workersThe restriction was safe at one size, but autoscaling introduces new egress addresses that were never added to the policy.SecurityIntermediate21 minPro NETWORK-028TLS handshake fails only through one CDN POPTLS handshake fails only (Certificate Trust Failure) is a hands-on troubleshooting drill. Most regions succeed, but a single edge location negotiates an older TLS path and breaks the request. Azure Firewall and Proxy Paths needs to be checked by narrowing scope, recent change,...NetworkIntermediate22 minPro LINUX-128PAM faillock works on local users, but NFS-backed home directory latency makes remote users appear to authenticate and then fail session setupPassword checks succeed, yet login still breaks because account and session modules depend on slow remote state.LinuxIntermediate16 minPro
