Clarifying Questions (3 minute)

• Looking at the timing, I'm thinking this might be a recent development. When exactly did customers start reporting increased latency?

Why it matters: Pinpointing the timeframe helps correlate the issue with recent changes or events. Expected answer: Reports started coming in about a week ago. Impact on approach: A sudden onset suggests a specific trigger rather than gradual degradation.

• Considering the nature of CASB services, I'm wondering about the scale. What percentage of customers are affected by this latency issue?

Why it matters: Determines if it's a widespread problem or limited to specific user segments. Expected answer: Approximately 30% of customers have reported issues. Impact on approach: A significant percentage indicates a systemic problem rather than isolated incidents.

• Given the critical nature of CASB in security infrastructure, I'm curious about the severity. How much has the latency increased compared to normal operation?

Why it matters: Helps quantify the impact and urgency of the problem. Expected answer: Latency has increased by an average of 200-300 milliseconds. Impact on approach: Significant increase suggests looking at core infrastructure or major configuration changes.

• Thinking about potential changes, have there been any recent updates to the CASB service or underlying infrastructure?

Why it matters: Recent changes are often correlated with performance issues. Expected answer: A minor update was pushed last week to enhance DLP capabilities. Impact on approach: Focus on the recent update as a potential cause, examining its implementation and impact.
