• Looking at the timing, I'm thinking there might be a recent change in our infrastructure. Has there been any significant update to our video delivery system in the past month?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, we migrated to a new CDN provider. Impact on approach: If confirmed, we'd focus on CDN-related issues first.

• Considering user segments, I'm curious if this is affecting all users equally. Are we seeing any patterns in terms of geography, device type, or content type?

Why it matters: Segmentation helps narrow down potential causes. Expected answer: Mobile users in certain regions are more affected. Impact on approach: We'd prioritize mobile-specific and regional CDN investigations.

• Given the specific 15% increase, I'm wondering about our measurement accuracy. Have there been any changes to how we track or define buffering errors?

Why it matters: Ensures we're addressing a real issue, not a measurement anomaly. Expected answer: No changes in measurement methodology. Impact on approach: Confirms we're dealing with an actual performance degradation.

• Thinking about user behavior, has there been any significant change in the type or volume of content being accessed?

Why it matters: Changes in usage patterns can strain existing systems. Expected answer: There's been a 20% increase in 4K video uploads. Impact on approach: We'd focus on high-resolution video handling and storage systems.
