Why has Peraton's satellite ground system experienced a 15% increase in latency over the past month?

Introduction

Peraton's satellite ground system has experienced a 15% increase in latency over the past month, potentially impacting critical operations and customer satisfaction. To address this issue, I'll employ a systematic approach to identify, validate, and resolve the root cause while considering both immediate and long-term implications.

Clarifying Questions (3 minutes)

• Considering the timing, I'm wondering if there have been any recent system upgrades or changes. Have any modifications been made to the satellite ground system in the past 1-2 months?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, a software update was implemented. Impact on approach: If confirmed, I'd focus on the update's impact and potential rollback options.

• Given the specific 15% increase, I'm curious about the baseline performance. What was the average latency before this increase occurred?

Why it matters: Understanding the baseline helps quantify the impact and set realistic improvement targets. Expected answer: The average latency was around 100ms. Impact on approach: This would help determine if the increase is significant enough to warrant immediate action.

• Thinking about potential external factors, have there been any unusual weather patterns or solar activities reported recently?

Why it matters: Environmental factors can significantly impact satellite communications. Expected answer: No significant anomalies reported. Impact on approach: If confirmed, I'd shift focus to internal system issues rather than external factors.

• Considering user impact, are all customers experiencing this latency increase uniformly, or is it affecting specific regions or user groups?

Why it matters: Localized issues might indicate different root causes than system-wide problems. Expected answer: The issue appears to be system-wide. Impact on approach: A system-wide issue would lead me to investigate core infrastructure components.
