The Central Authentication Service (CAS) application servers had a connection issue to its back-end database server starting around 9:49 pm on
Dec. 10. This prevented some users from logging in. The servers have been restarted and CAS service has returned to normal at 8:45 am, Dec. 20. CCS technical team is investigating the root cause.
We apologize for any inconvenience this may have caused.
