Date Time Trigger Automation Failues
Starting on **April 20th, 2026 at 10:00 AM PDT**, a combination of scaled-up background action jobs in the EU and a recent change to how date time trigger volume is managed overloaded the system that processes resource intensive background action jobs. This caused multi-hour delays in email and inbox notifications in the EU and prevented date time triggers from executing in all regions. Engineers were first alerted on **April 21st** by our monitoring systems, but did not recognize the full scope of the incident until **April 23rd**. On April 23rd, the change to manage date time trigger volume was reverted and the problematic background action jobs were isolated. All delayed notifications were sent by **April 24th, 11:30 AM PDT**, and all delayed date time triggers were executed by **April 27th, 4:00 AM PDT**.
