What factors are causing the increased latency in Gogo's 2Ku satellite internet system on international flights this month?

Introduction

Increased latency in Gogo's 2Ku satellite internet system on international flights 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 Gogo's service quality and customer satisfaction.

I'll approach this problem by first clarifying the context, then ruling out external factors before diving deep into the product ecosystem, metric breakdown, and data analysis. From there, I'll form and validate hypotheses, conduct root cause analysis, and propose a comprehensive resolution plan.

Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change in satellite coverage or capacity. Has there been any modification to our satellite network or partnerships in the past month?

Why it matters: Changes in satellite infrastructure could directly impact latency. Expected answer: No major changes to satellite partnerships or coverage. Impact on approach: If true, we'd focus more on software or hardware issues on aircraft.

• Considering user segments, I'm curious about the flight routes experiencing the most significant latency increases. Are we seeing this issue uniformly across all international routes or are certain regions more affected?

Why it matters: Regional patterns could indicate issues with specific satellites or ground stations. Expected answer: Higher latency on trans-Pacific routes. Impact on approach: We'd investigate satellite coverage and capacity in the Pacific region.

• Regarding performance metrics, has there been any change in how we measure or define latency in the past month?

Why it matters: Ensures we're comparing apples to apples in our data analysis. Expected answer: No changes to latency measurement methodology. Impact on approach: Confirms the issue is real and not a result of measurement changes.

• Thinking about recent product changes, have we rolled out any software updates to the 2Ku system in the last 30-60 days?

Why it matters: Software updates can introduce unexpected performance issues. Expected answer: A minor firmware update was pushed to 2Ku systems two weeks ago. Impact on approach: We'd prioritize investigating the impact of this recent update.
