Clarifying Questions (3 minutes)

• I'm noticing the timeframe mentioned. Has there been any significant change in deployment volume or patterns in the last month?

Why it matters: Changes in deployment patterns could stress the system in new ways. Expected answer: No significant changes in volume or patterns. Impact on approach: If true, we'd focus more on system changes or external factors.

• Considering the nature of Site Factory, are these errors occurring across all customer sites or concentrated in specific segments?

Why it matters: Helps determine if this is a systemic issue or limited to certain use cases. Expected answer: Errors are widespread but with some variation across segments. Impact on approach: Would guide our investigation towards common infrastructure vs. specific configurations.

• Have there been any recent updates to the Site Factory platform or underlying infrastructure?

Why it matters: Recent changes are often correlated with performance issues. Expected answer: A minor update was rolled out three weeks ago. Impact on approach: Would focus initial investigation on the impact of this update.

• Are we seeing any patterns in the types of errors being reported?

Why it matters: Different error types point to different root causes. Expected answer: There's an increase in timeout errors and database connection failures. Impact on approach: Would guide our technical investigation towards specific components.

• Has there been any change in how we're measuring or defining error rates?

Why it matters: Ensures we're comparing apples to apples in our metrics. Expected answer: No changes in measurement or definition. Impact on approach: Confirms the issue is real and not a result of changed metrics.
