Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a correlation with recent system changes. Have there been any updates or deployments to the real-time bidding system in the past week?

Why it matters: Recent changes often trigger unexpected issues. Expected answer: Yes, a minor update was deployed. Impact on approach: If confirmed, we'd focus on the update's specifics and rollback options.

• Considering the nature of real-time bidding, I'm curious about traffic patterns. Has there been any unusual spike in bidding requests or changes in traffic sources recently?

Why it matters: Abnormal traffic could strain the system, causing errors. Expected answer: Traffic has been within normal ranges. Impact on approach: If traffic is normal, we'd shift focus to internal system issues.

• Given the complexity of real-time bidding systems, I'm wondering about the specific error types we're seeing. Can you provide more details on the nature of these errors – are they timeout errors, bid calculation errors, or something else?

Why it matters: Different error types point to different root causes. Expected answer: Mostly timeout errors with some bid calculation errors. Impact on approach: This would guide our investigation towards system performance and algorithm efficiency.

• Thinking about the broader ecosystem, I'm curious if this issue is isolated to specific ad exchanges or if it's affecting all integrations equally?

Why it matters: Isolated issues might indicate problems with specific integrations. Expected answer: The issue appears to be affecting all exchanges similarly. Impact on approach: A universal issue would suggest an internal system problem rather than an integration-specific one.
