NOC incident correlation — 503 under load
A tool 503s during the incident; retry/backoff plus a cached fallback keeps it moving.

Context
An NOC agent correlating a network incident hits a 503 on the topology service — overloaded by the very incident it's diagnosing. Retry with backoff, then fall back to the cached topology, flagging staleness.
The decision
Resilience here is a network-SLA duty, not a nicety — the tools you depend on are least available exactly when the incident is worst, so the recovery policy is the design.
What most miss
Demos assume tools are up. In a real incident the dependency is overloaded precisely when you need it; the backoff-and-cache path is what keeps the agent useful under load.
Stakes
An agent that stalls on a 503 mid-incident extends the outage it was meant to shorten.
