The main issue affecting Rainbow services has been resolved, and all other services are now operating normally. However, the calendar presence feature remains unavailable. An intervention on our production infrastructure is required to restore this functionality, but it cannot be performed at this time. We will provide further information tomorrow regarding the next steps. If you are still experiencing any other issues, please open a support ticket so our teams can investigate.

## Post-Event Review ### Summary & Impact On October 20, 2026, Rainbow users experienced performance degradation across several services, resulting in increased response times and unavailability of the Calendar service. ### Root Cause Investigations identified a database indexing issue that increased query processing times. ### Resolution Our technical teams fixed the index issue and stabilized the platform. Database performance was restored, and the Calendar services were progressively restarted across the different regions. Normal service performance was subsequently restored. ### Preventive Actions Additional safeguards have been implemented to prevent similar database indexing issues and improve platform stability.

Our teams have made progress on the issue affecting some Rainbow Hub customers. The issue is linked to a recent platform change affecting how transfers are handled. A fix has been developed and is being validated. We will share the deployment schedule as soon as validation is complete. Until the fix is deployed, we recommend: * using blind (direct) transfer instead of attended transfer, or * answering and transferring Call Queue calls from the Rainbow application on a PC. Our teams remain fully engaged to resolve this issue as quickly as possible.

**Scheduled Deployment Update** Final validation testing has been successfully completed. A fix for the **Rainbow Hub Call Queue attended transfer issue** is scheduled for deployment in **EMEA today, September 29, at 21:00 CEST**. During the deployment window, a service interruption of up to **10 minutes** may occur. The service will be closely monitored following deployment, and we will provide a further update once the rollout has been completed. Thank you for your patience and understanding.

**Monitoring** The fix for the Rainbow Hub Call Queue attended transfer issue was deployed yesterday at **21:00 CET**, as planned. We are currently monitoring the service and the fix is performing as expected.
