We will be performing unplanned maintenance on the JupyterHub server to address CVE-2019-5736. This is a critical security bug with the Docker container runtime. The JupyterHub server will be down for a few minutes while the updates are applied. Your existing Notebook servers should come back automatically once the maintenance is finished.
Update: this took a bit longer than expected, but the JupyterHub server is back up after the maintenance. Thank you for your patience.
