What factors are causing the increased error rate in OneTrust's Data Discovery scans for cloud environments in the last two weeks?

Introduction

The increased error rate in OneTrust's Data Discovery scans for cloud environments over the past two weeks is a critical issue that demands immediate attention. This analysis will systematically identify, validate, and address the root cause while considering both short-term fixes and long-term implications for our product strategy.

I'll approach this problem by first clarifying key details, ruling out external factors, and then diving deep into our product ecosystem. We'll break down the metric, gather relevant data, form hypotheses, and conduct a thorough root cause analysis. Finally, we'll develop a comprehensive plan to validate our findings and implement solutions.

Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might have been a recent update or change. Has there been any significant product or infrastructure changes in the last month?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, there was a cloud infrastructure update two weeks ago. Impact on approach: If confirmed, we'd focus on the update's impact on scan processes.

• Given the specificity to cloud environments, I'm curious about our data center scans. Are we seeing similar error rate increases in on-premises environments?

Why it matters: Helps isolate whether the issue is cloud-specific or more widespread. Expected answer: No, on-premises scans are unaffected. Impact on approach: We'd narrow our focus to cloud-specific components and configurations.

• Considering user segments, are all cloud providers (AWS, Azure, GCP) equally affected, or is the issue more pronounced with a specific provider?

Why it matters: Identifies if the problem is universal or provider-specific. Expected answer: The issue is more severe with AWS environments. Impact on approach: We'd investigate AWS-specific integrations or recent changes in their APIs.

• Regarding the error rate metric, has there been any change in how we're measuring or reporting these errors in the last month?

Why it matters: Ensures we're not dealing with a measurement anomaly rather than an actual performance issue. Expected answer: No changes to error measurement or reporting. Impact on approach: Confirms the issue is with the scans themselves, not our monitoring.
