CISL system engineers will update the JupyterHub deployment on Tuesday, December 14. The update will begin before 8 a.m. MST and is expected to take less than 30 minutes to complete. The work will include general package and extension updates that are expected to provide a more stable user experience. CISL will make every effort to minimize impacts but users may experience brief interruptions while the updates are in progress, and any JupyterHub sessions running when the updates begin may be killed.
