Facebook releases Safety Check crisis response tool for Workplace

This post details the adaptation of Facebook's Safety Check feature for the Workplace platform. Key technical contributions include migrating storage to TAO for enterprise scale, developing a custom access management module for enhanced privacy, implementing a location parser to standardize company-specific location data, and designing a multi-channel notification system with per-person job handling and retry logic for reliability. The 'iterate' phase utilizes graph storage for real-time status updates and a queuing system to manage response volume, leveraging GraphQL subscriptions for real-time updates.
