JupyterHub not starting up

Notice: Kubernetes PVC Attachment Errors Due to GCP Incident (June 12, 2025)

We are aware of an ongoing issue where some users may see errors when starting their JupyterHub environments. Affected users may encounter errors similar to:

Root cause:
This is due to a Google Cloud Platform (GCP) service disruption that is intermittently preventing Kubernetes from attaching persistent volumes. The issue is upstream of our environment and is being actively addressed by Google (see GCP Status).

What should you do:

• If you encounter this error when launching your JupyterHub environment, no action is needed on your part.

• In most cases, the issue is temporary and will resolve automatically as the underlying cloud services recover.

• We recommend waiting a few minutes and then retrying.

• Please avoid repeated restarts or resubmissions, as Kubernetes will continue to attempt recovery automatically.

We will continue to monitor the situation and will update as more information becomes available. Thank you for your patience.

Best regards,

Komal
