Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change in network configuration. Has there been any significant update to the DDC network architecture in the past month?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, a new routing algorithm was implemented. Impact on approach: If confirmed, we'd focus on the new algorithm's impact on latency.

• Considering user segments, I'm curious about the distribution of latency increase. Is the 30% increase uniform across all customers, or are certain types of users more affected?

Why it matters: Helps identify if the issue is systemic or user-specific. Expected answer: Enterprise customers are experiencing higher latency spikes. Impact on approach: We'd investigate enterprise-specific configurations or usage patterns.

• Given the geographical focus, I'm wondering about any North America-specific factors. Have there been any notable changes in network traffic patterns or volumes in this region recently?

Why it matters: Regional factors could explain the localized nature of the issue. Expected answer: There's been a 20% increase in video streaming traffic. Impact on approach: We'd analyze how the DDC solution handles increased video traffic.

• Considering potential measurement issues, has there been any change in how latency is measured or reported in the last quarter?

Why it matters: Ensures the observed increase is real and not a result of changed metrics. Expected answer: No changes in measurement methods. Impact on approach: Confirms we're dealing with an actual performance issue, not a reporting anomaly.
