Why these questions matter:
- Understanding the scale helps prioritize our response
- Timing could reveal correlations with recent changes or external events
- User segmentation might point to specific infrastructure or regional issues
- Recent changes could be the direct cause of the problem
- Content patterns might indicate issues with specific encoding or delivery methods
- Measurement changes could explain the spike without an actual increase in buffering
Hypothetical answers and their impact:
- 150% increase over the past week - This suggests a sudden, significant problem requiring immediate action
- Spike started 3 days ago and has been consistent - Points to a recent change or event as the likely cause
- Users in Southeast Asia are disproportionately affected - Indicates a potential regional infrastructure issue
- New CDN provider onboarded last week - Highly likely to be related to the buffering issues
- 4K content showing more buffering - Suggests bandwidth or encoding problems for high-quality streams
- No changes in measurement - Confirms the spike is real and not a data anomaly
