From approximately 2pm to 2:15pm our authentication services (SSO) performance was degraded. CUIT has resolved the issue and believes it is now resolved. We will continue to closely monitor the service to ensure it is working as expected. We apologize for any inconvenience this may cause and thank you for your patience. If you have any questions or continue to have issues, please contact your support team. Faculty Support: 212-854-6097/ facsup@gsb.columbia.edu
