Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this might be a recent change. When did you first notice this increase in sync time?

Why it matters: Helps pinpoint potential triggers or changes that coincided with the issue. Expected answer: Within the last week or two. Impact on approach: Recent changes would focus our investigation on recent deployments or system modifications.

• Considering user impact, I'm curious about the scope. Is this affecting all users or a specific segment?

Why it matters: Determines if it's a global issue or limited to certain user groups or regions. Expected answer: It's affecting a majority of users across different regions. Impact on approach: A widespread issue suggests a core system problem rather than a localized one.

• Given the nature of sync operations, I'm wondering about data volume. Has there been a significant increase in the amount of data being synced recently?

Why it matters: Could indicate if the system is struggling with increased load. Expected answer: No unusual spikes in data volume have been observed. Impact on approach: If data volume isn't the cause, we'd focus more on system performance or architectural issues.

• Thinking about system dependencies, have there been any recent changes to APIs or third-party services that the inbox sync relies on?

Why it matters: External dependencies could be causing bottlenecks. Expected answer: No major changes to external services have been reported. Impact on approach: If confirmed, we'd shift focus to internal systems and recent code deployments.

• Considering performance metrics, has there been any change in error rates or other related metrics alongside the increased sync time?

Why it matters: Correlated changes in other metrics could provide additional clues. Expected answer: There's been a slight increase in timeout errors. Impact on approach: This would guide us to investigate potential timeout issues or resource constraints.
