You arrive in the office to find Facebook Lite opens on Android are down 10%. How would you diagnose the issue?

To diagnose a 10% drop in Facebook Lite opens on Android, I would first confirm the scope and definition of "opens" (e.g., app launches, session starts). Then, I'd investigate several key areas: Monitoring & Alerting: Check our internal dashboards and alerting systems for any anomalies or specific error messages related to Facebook Lite on Android. This includes server-side metrics, API health, and client-side crash reports. Recent Deployments: Review recent code deployments, feature flag changes, or infrastructure updates that might have coincided with the drop. A rollback might be necessary if a recent change is suspected. User Impact: Analyze user-reported issues, app store reviews, and social media mentions for any common themes or specific device/OS versions affected. External Factors: Consider external influences such as network issues in key regions, changes in Android OS versions, or even competitor activity. A/B Tests: If any A/B tests are running on Facebook Lite for Android, check their performance and impact on opens. Data Pipeline: Ensure data collection and reporting pipelines are functioning correctly and not introducing artificial drops.
