   We're investigating an issue affecting Proactive Monitoring limit alerts, where some customers may not receive expected notifications. The impact is limited to customers using the affected limit monitoring functionality, and the underlying Salesforce services remain available. We've narrowed the investigation to the processing of specific monitoring data used to generate these alerts and are working to restore normal alerting functionality. We'll provide another update in 30 minutes or sooner if additional information becomes available.

   We're continuing to investigate the issue affecting Proactive Monitoring limit alerts for a subset of customers. Our investigation confirms that other monitoring data continues to process normally, and the issue remains isolated to the specific monitoring data used to generate these limit alerts. We've validated the broader monitoring pipeline and are continuing to investigate why the affected limit-monitoring data is not being generated as expected. We'll provide another update in 60 minutes or sooner if additional information becomes available.

We'll provide another update once the rolling restarts have completed, or sooner if additional information becomes available.
