Facebook Logins are going down. What would you do?

Introduction

Facebook logins declining is a critical issue that demands immediate attention. As the VP of Product, I'll approach this problem systematically to identify, validate, and address the root cause while considering both short-term fixes and long-term implications.

I'll begin by clarifying the scope of the issue, then analyze potential external factors before diving deep into internal causes. My approach will involve breaking down the login process, examining relevant metrics, and forming data-driven hypotheses. Finally, I'll propose a structured plan for validation and resolution.

Step 1

Clarifying Questions (3 minutes)

• What's the specific timeframe for the login decline?

• Are all user segments affected equally, or are there variations?

• Have we observed any changes in login success rates or error types?

• Are there any recent product updates or system changes that coincide with the decline?

• Has the definition or measurement of login attempts changed recently?

• Are we seeing similar trends across all platforms (web, mobile, third-party integrations)?

Why this matters: Understanding the context helps narrow down potential causes and guides our investigation.

Hypothetical answer: Let's assume we've seen a 15% decline in successful logins over the past week, affecting all user segments but more pronounced on mobile platforms. No recent product updates, but we did perform a routine server maintenance three days ago.

Impact on approach: This information suggests we should focus on mobile-specific issues and recent infrastructure changes in our initial investigation.
