Clarifying Questions (3 minutes)

• Given the timing, I'm wondering about recent updates. Have there been any significant changes to Aura's codebase or infrastructure in the past quarter?

Why it matters: Recent changes could directly impact the discovery process. Expected answer: Yes, there was a major update to the discovery algorithm. Impact on approach: If confirmed, we'd focus on regression testing and code review.

• Considering user segments, I'm curious about the error distribution. Is the increased error rate uniform across all network sizes and types, or is it more pronounced in specific segments?

Why it matters: This helps identify if the issue is global or segment-specific. Expected answer: The error rate is higher in large enterprise networks. Impact on approach: We'd prioritize investigating scalability issues and enterprise-specific features.

• Thinking about performance metrics, I'm interested in the error rate trend. Has the increase been gradual over the quarter, or was there a sudden spike at any point?

Why it matters: The pattern could indicate whether it's a cumulative issue or tied to a specific event. Expected answer: There was a sudden spike mid-quarter. Impact on approach: We'd focus on identifying any correlated events or changes around that time.

• Regarding system health, I'm wondering about resource utilization. Have there been any notable changes in CPU, memory, or network usage during the discovery process?

Why it matters: Resource constraints could be causing the increased error rate. Expected answer: CPU usage has increased significantly during discovery. Impact on approach: We'd investigate potential performance bottlenecks and optimization opportunities.
