Production issue face :-

Root cause: A bad deploy pushed a config change that pointed our data ingestion pipeline to a deprecated API endpoint. The ingestion jobs kept silently failing with no alerts fired because the health checks were checking the wrong service layer.

How I fixed it:

1. Rolled back the config to the last known-good version

2. Restarted the ingestion workers for all three league connectors (NBA, NFL, MLS/EPL)

3. Backfilled the 4-hour gap in player stats and scoring event data

4. Patched the health check to actually validate data freshness, not just service uptime
