Clarifying Questions (3 minutes)

• Given the specific 45% figure, I'm wondering about the data source. Could you confirm if this percentage is based on server-side logs or client-side telemetry?

Why it matters: Understanding the data source helps determine the reliability of the metric and potential blind spots. Expected answer: Server-side logs Impact on approach: Server-side data might miss client-side issues, prompting investigation into front-end problems.

• Considering the nature of shared albums, I'm curious about the timeline. Has this 45% non-loading rate been consistent, or did it spike recently?

Why it matters: A sudden spike could indicate a recent change or external event, while a consistent issue might suggest a long-standing problem. Expected answer: Recent spike in the last week Impact on approach: A recent spike would focus our investigation on recent changes or external factors.

• Looking at user segments, I'm thinking about device types. Is this issue more prevalent on mobile devices, desktop, or evenly distributed?

Why it matters: Device-specific issues could narrow down the problem to certain platforms or browsers. Expected answer: More prevalent on mobile devices Impact on approach: Mobile prevalence would shift focus to mobile-specific factors like app versions or OS updates.

• Considering potential system changes, have there been any recent updates to the sharing mechanism or content delivery network?

Why it matters: Recent changes often correlate with new issues and could provide a starting point for investigation. Expected answer: Minor update to sharing API last week Impact on approach: This would prioritize investigation of the API change and its potential downstream effects.
