Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent network change. Has there been any significant infrastructure updates or maintenance in the Mumbai area recently?

Why it matters: Network changes often precede performance issues. Expected answer: Yes, there was a recent upgrade to some cell towers. Impact on approach: If confirmed, we'd focus on the upgrade process and potential rollback options.

• Considering user segments, I'm curious about the distribution of complaints. Are we seeing this issue across all user types or is it concentrated in specific areas or demographics?

Why it matters: Helps identify if it's a localized or widespread problem. Expected answer: Complaints are primarily from business districts during peak hours. Impact on approach: We'd investigate capacity issues in high-density areas during busy times.

• Given the sudden nature, I'm wondering about external factors. Have there been any major events or changes in Mumbai that could be affecting network usage patterns?

Why it matters: External events can dramatically shift network demand. Expected answer: A large tech conference is currently happening in the city. Impact on approach: We'd look into temporary capacity solutions for event areas.

• Thinking about measurement accuracy, has there been any change in how we're collecting or analyzing network speed data?

Why it matters: Ensures we're not dealing with a data anomaly rather than an actual performance issue. Expected answer: No changes to data collection or analysis methods. Impact on approach: We'd focus on actual network performance rather than measurement issues.
