Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be related to a recent update. Has there been any recent deployment or changes to the HTTP connector or related systems?

Why it matters: Recent changes often correlate with sudden performance shifts. Expected answer: Yes, there was a minor update to the connector last week. Impact on approach: If confirmed, we'd focus on the update's contents and rollout process.

• Considering the scope, I'm curious about the extent of the issue. What percentage of HTTP connector integrations are experiencing increased error rates?

Why it matters: This helps determine if it's a widespread issue or limited to specific use cases. Expected answer: Approximately 30% of integrations are affected. Impact on approach: A high percentage would suggest a systemic issue rather than isolated incidents.

• Given the nature of HTTP connectors, I'm wondering about the types of errors being reported. Are we seeing specific error codes or a general increase across all error types?

Why it matters: Different error types point to different root causes. Expected answer: There's a significant increase in 503 Service Unavailable errors. Impact on approach: This would direct our investigation towards server-side issues or capacity problems.

• Thinking about potential external factors, have there been any significant changes in usage patterns or traffic volume for the affected integrations?

Why it matters: Unusual traffic patterns could explain performance degradation. Expected answer: No significant changes in overall usage have been observed. Impact on approach: This would rule out capacity issues and focus on internal system changes.
