Rainbow Outage History

We have identified the cause of the issue affecting Rainbow services. The system is currently recovering, and our technical teams are closely monitoring the situation. However, an issue with the calendar presence status on Rainbow is still ongoing. We will provide further updates as the situation progresses.

OVHcloud has confirmed a network connectivity issue between Orange and OVHcloud. Their teams are working to restore normal connectivity. Users in France accessing Rainbow through an Orange internet connection may experience slow performance or intermittent access issues. You can follow the provider’s updates here: We will share further updates as more information becomes available.

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.

Our investigation has identified intermittent network instability within the underlying infrastructure. As a result, some users may experience difficulties accessing certain Rainbow services, including starting or joining Bubble calls. The issue has been escalated to our hosting provider, and our technical teams are continuing to monitor the situation. We will provide further updates as soon as more information becomes available.

We have identified the faulty workflow responsible for the audio issues experienced by affected end users. Our investigation has determined that, under several network conditions, the media relay tunnel establishment between the application software and the core media component does not complete as expected. As a result, audio is available only for a few seconds before being interrupted. The root cause has been identified, and our engineering teams are currently working on a solution. We will provide further updates as progress is made and a remediation plan is finalized. We apologize for the inconvenience and appreciate your patience while we work to resolve this issue.

We have identified the solution and are currently working on its implementation. Testing activities are scheduled in the coming days to validate the fix and ensure service stability. Our objective is to deploy the solution to production by the middle of next week, following the successful completion of regression testing. We will continue to monitor progress closely and provide further updates as milestones are reached. We appreciate your continued partnership and will keep you informed of further developments.

Problem is identified we are going to apply the fix

Our teams have identified the origin of the incident. Mitigation actions are in progress, including cleanup and restart of the impacted component. Service recovery is underway, and we will continue to keep you informed.
