Clarifying Questions (3 minutes)

• Given the scale of the issue, I'm thinking this might be a recent development. Has this 40% failure rate been consistent, or did it spike suddenly?

Why it matters: Understanding the timeline helps identify potential triggers or changes that led to the issue. Expected answer: The problem emerged suddenly in the last week. Impact on approach: A sudden spike would point towards recent changes or external factors.

• Considering user segments, I'm wondering if this issue is affecting all users equally. Are we seeing any patterns in terms of device types, operating systems, or geographical regions?

Why it matters: This information helps narrow down potential technical or infrastructure-related causes. Expected answer: The issue is more prevalent on Android devices and in certain regions. Impact on approach: This would focus our investigation on Android-specific factors and regional infrastructure.

• Looking at the upload process, I'm curious about where exactly the sync failure is occurring. Is it happening during the upload, processing, or playback stage?

Why it matters: Pinpointing the stage of failure helps isolate the problem area in the system. Expected answer: The sync issue is primarily occurring during the processing stage. Impact on approach: This would direct our attention to the video processing pipeline and associated services.

• Considering recent changes, have there been any updates to the Reels feature, backend systems, or content delivery network in the past month?

Why it matters: Recent changes often correlate with new issues and can provide immediate areas for investigation. Expected answer: A backend update was rolled out two weeks ago to improve processing speed. Impact on approach: This would make the recent update a prime suspect for investigation.
