Timed challenge
Make the SLO green
go-api's SLO is breaching — the service selector is broken and no traffic is reaching pods. The SRE dashboard shows the error rate above the threshold. Fix the root cause and confirm the SLO recovers.
ConfigPar 12m−5 per hint
Definition on GitHubHow it is scored
- Par time is 12m. Beating it scores higher; the clock starts when you do.
- Each hint costs 5 points. Taking one is often still the right call.
- Grading is a real check against the live cluster, so a fix that only looks right scores nothing.
What gets set up
Starts from the service-selector-broken incident, injected for you before the timer begins.
