At 1:45 pm, July 3, 2011, access to major systems including R-Mail and my.ryerson.ca was interrupted due to a problem with a redundant link on the firewall cluster that protects those systems.
The problem was resolved @ 2:53 pm. Access to all systems has been restored.
After 3:30 pm problems with the firewall cluster resurfaced. CCS staff are working to restore the system.
We apologize for the interruption to services.

Following the upgrade to GroupWise 8 on our servers, we experienced three serious incidents last week where a post office became unresponsive. The vendor, Novell, recommended we apply a performance patch to our GroupWise servers and update the server operating system. The GroupWise patches were applied on Saturday and the operating systems updated on Sunday. We hope these changes will resolve the GroupWise performance issues we experienced last week and will continue to monitor the system carefully.

Following Saturday’s upgrade of our Groupwise servers to Groupwise 8, one of our Groupwise servers (PO2) began performing very poorly. At times the system was so slow that it was impossible to log in. The vendor has suggested we apply a software patch to resolve the problem. The patch will be applied at 9 PM this evening during a brief outage.

Ryerson’s Central Authentication Service (CAS) stopped working correctly on Tuesday, June 14 around 5:45 PM. The problem was traced to an intermittent connection problem that was fixed at 6:55 PM. CAS is the system that controls access to the my.ryerson.ca portal and therefore applications such as RAMSS, eHR, and the Blackboard Learning Management System. During the outage many people could not log into the my.ryerson.ca portal and the applications it hosts. We are investigating how to prevent this problem from recurring in the future.
Please accept our apologies for this unplanned outage.
