Front change history: [by_company_00017] Front App Outage

Front reported a major outage affecting App, Calendar, and Rules and Workflows from 2025-11-21 19:21 UTC to 2025-11-21 22:18 UTC (2 h 56 min). A rollback began recovering failures in us-west-1, though rules and calendar delays persisted during recovery. Front linked the problem to a deployment changing internal caching connections and an environment-specific caching configuration.
