   At 00:49 UTC on May 16, 2026, we noted a performance degradation impacting the synchronization of email and calendar events. As a result, some customers may experience significant delays in email and calendar events syncing successfully. Initial investigation has determined the issue is related to an unintended autoscaling operation affecting specific node pools. Engineering teams are actively working to stabilize the impacted infrastructure, prevent additional scale-down activity, and restore normal processing performance. We will provide another update within 30 minutes or sooner if additional information becomes available.

   We have implemented corrective actions to stabilize the impacted infrastructure and have mitigated high-traffic data sources contributing to the delays. While we are seeing a steady improvement in processing rates, customers with the Einstein Activity Capture (EAC) feature enabled may continue to experience delays in email and calendar event synchronization as the remaining backlog of events is processed. We are closely monitoring the service as performance levels return to normal. We will provide another update upon significant update or sooner if additional information becomes available.
