Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change in the encryption algorithm. Has there been any update to the encryption protocols or libraries in the last quarter?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, there was an update to improve security. Impact on approach: If confirmed, we'd focus on the update's implementation and compatibility.

• Considering user behavior, I'm curious about usage patterns. Have we seen any significant changes in the volume or type of emails being encrypted?

Why it matters: Unusual usage patterns could strain the system. Expected answer: There's been a 20% increase in encrypted emails. Impact on approach: We'd investigate scalability and capacity issues if confirmed.

• Thinking about system dependencies, I wonder about our infrastructure. Have there been any changes to our server configurations or network architecture?

Why it matters: Infrastructure changes can impact feature performance. Expected answer: Some load balancers were reconfigured last month. Impact on approach: We'd examine the load distribution and server performance if true.

• Considering external factors, I'm interested in any changes to email client compatibility. Have any major email clients updated their software in ways that might affect our encryption?

Why it matters: Client-side changes can disrupt our encryption process. Expected answer: Gmail rolled out a new security feature last month. Impact on approach: We'd investigate compatibility issues with specific clients if confirmed.
