After: The potential root cause identified, and fix is underway
Before: not present
After: We identified and resolved an infrastructure configuration issue that was causing authentication failures and deployment access errors across the platform. The root cause was a network configuration change during an infrastructure upgrade that temporarily disrupted connectivity between our control plane and customer deployments.
The fix has been applied and initial validation confirms services are recovering
We are actively monitoring to confirm full recovery across all affected deployments. If you are still experiencing issues, please contact support.
Before: not present
After: The issue has been fully resolved. All services, including authentication, deployment access, and DAG visibility, are operating normally.
