Clarifying Questions (3 minute)

• Looking at the timing, I'm thinking there might be a recent change. Have there been any updates to the proxy service or related systems in the last month?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, a minor update was deployed two weeks ago. Impact on approach: If confirmed, I'd focus on changes in that update.

• Considering the scope, I'm wondering about the extent of the problem. Is this latency increase affecting all customers equally, or are there patterns in terms of geography, database type, or usage volume?

Why it matters: Patterns could indicate specific infrastructure or scaling issues. Expected answer: Larger customers in certain regions are more affected. Impact on approach: I'd investigate regional infrastructure and high-load scenarios.

• Given the nature of proxy services, I'm curious about network factors. Have there been any changes in network topology, DNS, or CDN configurations recently?

Why it matters: Network changes can significantly impact latency. Expected answer: No major network changes reported. Impact on approach: I'd shift focus to application-level issues if confirmed.

• Thinking about external factors, I'm considering potential changes in usage patterns. Has there been a significant increase in overall traffic or changes in how customers are using the service?

Why it matters: Unexpected load or usage changes could strain the system. Expected answer: Usage has been growing steadily, no sudden spikes. Impact on approach: I'd look into gradual scaling issues if confirmed.
