## Timeline of updates

- **identified** 2026-05-08 04:35 UTC: Starting at 11:45 PM ET, Braze customers on our US05 have been experiencing latency across campaign/canvas processing, data processing, and message sending due to an ongoing issue with an upstream provider (AWS).  We are working on a fix. Please see https://health.aws.amazon.com/health/status for more details.
- **identified** 2026-05-08 05:04 UTC: We are continuing to experience delays in Campaign & Canvas Processing, Data Processing, and Message Sending. Additionally, Dashboard navigation is intermittently erroring. We are continuing to work on a fix while we await updates from AWS.  Please see https://health.aws.amazon.com/health/status for more details.
- **monitoring** 2026-05-08 05:32 UTC: We have implemented a fix to mitigate the impact of the ongoing AWS incident in Availability Zone (use1-az4) in the US-EAST-1 region. At this point, latency and error rates have returned to normal levels for all services.  Additionally, AWS is reporting early signs of recovery. Please see https://health.aws.amazon.com/health/status for more details.
- **resolved** 2026-05-08 05:47 UTC: Latency and error rates have remained at normal levels for all services, post-implementation of our fix, and this incident is resolved.  We will continue to monitor the overall system health until AWS reports full recovery.  Please see https://health.aws.amazon.com/health/status for more details.
