We have identified the issue as a disruption to CW managed authentication. While actual health of cluster(s) are fine, anyone using CW managed authentication will be unable to authenticate due to an outage in our authentication service. While the authentication service is down, if you are able to bypass your CW managed Authentication, you will still be able to access your cluster(s). We are urgently working on a fix to our authentication service in parallel and will continue to post updates to this status page.

We believe this incident has been mitigated. A fix went out to our authentication service and we're seeing a return to cluster/console access . We are continuing to monitor to ensure stability. If you continue to experience any issues, please reach out to support: [email protected]
