Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be related to a recent deployment. Has there been any significant update or change to the Nebula platform in the past week?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, there was a minor update. Impact on approach: If yes, we'd focus on the update's components; if no, we'd look at external factors.

• Considering the scale of the issue, I'm wondering about its consistency. Is this latency increase uniform across all users and use cases, or are there specific segments more affected?

Why it matters: Helps narrow down potential causes and affected areas. Expected answer: It's affecting high-volume enterprise users more. Impact on approach: Segmented impact would lead us to investigate specific user workflows or data types.

• Given the nature of cloud platforms, I'm curious about resource allocation. Have there been any changes in how compute resources are distributed or any unusual spikes in demand?

Why it matters: Resource constraints often lead to performance issues. Expected answer: No significant changes noted. Impact on approach: If yes, we'd focus on scaling and resource management; if no, we'd look at other technical factors.

• Thinking about the broader ecosystem, I'm considering external dependencies. Have there been any reported issues with underlying cloud infrastructure providers or third-party services?

Why it matters: External dependencies can significantly impact performance. Expected answer: No major reported issues. Impact on approach: If yes, we'd coordinate with providers; if no, we'd focus more on internal systems.
