Clarifying Questions (3 minutes)

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

Why it matters: Helps determine if this is an ongoing issue or a recent change, guiding our investigation approach. Expected answer: A sudden spike in the last week. Impact on approach: A sudden change would focus our investigation on recent system modifications or external factors.

• Considering the complexity of label syncing, I'm wondering about the technical architecture. Is the label syncing process handled by a single system or distributed across multiple services?

Why it matters: Identifies potential points of failure and narrows down the scope of investigation. Expected answer: Distributed across multiple microservices. Impact on approach: Would lead us to investigate inter-service communication and data consistency issues.

• Given the specific 40% figure, I'm curious about the affected user segments. Are we seeing any patterns in terms of user types, conversation volumes, or geographic regions among the affected conversations?

Why it matters: Helps identify if the issue is isolated to specific user groups or usage patterns. Expected answer: Higher impact on high-volume business users in certain regions. Impact on approach: Would focus our investigation on scalability issues or region-specific infrastructure problems.

• Thinking about recent changes, have there been any significant updates to the Messenger Business platform or related systems in the past month?

Why it matters: Recent changes often correlate with new issues and can provide a starting point for investigation. Expected answer: A recent API update for label management. Impact on approach: Would lead us to scrutinize the new API implementation and its integration with existing systems.
