Ryerson’s Central Authentication Service (CAS) (which controls the login process to my.ryerson.ca, Google Apps at Ryerson, and other services) was unavailable this afternoon between 3:00 PM and 3:18 PM.
This outage was caused by a software firewall rule change. A temporary fix has been implemented and CCS continues to investigate the root cause
