Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might have been a recent update to the filtering algorithm. Has there been any change to the content filtering system in the past week?

Why it matters: Recent changes often correlate with sudden performance shifts. Expected answer: Yes, there was a minor update to improve detection accuracy. Impact on approach: If confirmed, we'd focus on the update's specifics and rollback considerations.

• Considering user segments, I'm curious about the distribution of false positives. Are we seeing this spike across all user types, or is it concentrated in specific segments?

Why it matters: Helps narrow down potential causes and affected areas. Expected answer: The spike is more pronounced in educational institution accounts. Impact on approach: We'd investigate factors specific to educational content and usage patterns.

• Regarding performance metrics, I'm wondering about the magnitude of the spike. Can you quantify the increase in false positives compared to normal levels?

Why it matters: Helps gauge the severity and urgency of the issue. Expected answer: False positives have increased by approximately 30%. Impact on approach: A significant increase would prioritize immediate action over gradual improvements.

• Thinking about external factors, have there been any notable internet-wide events or trends that could affect content classification?

Why it matters: External events can sometimes trigger unexpected behavior in filtering systems. Expected answer: No significant external events have been reported. Impact on approach: If confirmed, we'd focus more on internal factors and recent system changes.
