This is your execution layer.
⚡ QUICK FIX MATRIX
🧠 If AI is not working
🔴 Likely Cause
Gemini quota exceeded (429)
✅ Action
- Retry later
- Use fallback model
- Reduce request volume
📊 If data is missing
🔴 Likely Cause
External service failure (SEMRush, ClickHouse)
✅ Action
- Refresh data
- Wait for recovery
- Check service health
🔄 If tasks are stuck
🔴 Likely Cause
Celery / queue issue
✅ Action
- Re-trigger process
- Re-run crawl
- Restart workflow
🕷️ If crawl is stuck
🔴 Likely Cause
Timeout on large site
✅ Action
- Reset crawl
- Re-run
- Break into smaller batches
⚠️ If dashboard not loading
🔴 Likely Cause
Database or Redis issue
✅ Action
- Refresh
- Retry after 30–60 seconds

🧩 ADVANCED RESOLUTION PATTERNS
🔧 Pattern 1 — Retry with Backoff
Used when:
- API calls fail
- External services unstable
👉 Always retry before escalating
🔄 Pattern 2 — Fallback Systems
Used when:
- AI model unavailable
- Data provider fails
👉 Switch provider instead of blocking
🧠 Pattern 3 — Graceful Degradation
Used when:
- Partial data available
👉 Show partial results instead of failing
⚙️ Pattern 4 — Queue Recovery
Used when:
- Jobs stuck
👉 Re-trigger instead of waiting
💣 Pattern 5 — Scale Adjustment
Used when:
- Memory / limits hit
👉 Reduce load or increase capacity
🛡️ PREVENTION LAYER
🚨 Add Monitoring For:
- DB connections > 80%
- Queue depth spikes
- API rate limits
- AI quota usage
🔄 Always Implement:
- Retry logic
- Circuit breakers
- Async processing
- Idempotent actions
🧠 Design Principle
👉 Systems should fail gracefully, not completely
🎯 FINAL TAKEAWAY
There are only 3 real failure modes:
- System overloaded
- Dependency unavailable
- Process stuck
💡 Operational Insight
If you fix:
- Retries
- Queues
- Fallbacks
👉 You eliminate 80% of production issues
