Service Alerts

At approximately 8:00 AM this morning (Jan 1, 2013) the CAS authentication service became unresponsive. uPortal and RAMSS were also affected. We believe the problem is likely the same one that affected CAS on December 26 – a problem with the SSL accelerators:

The CAS web servers have been restarted at 8:40 AM but not all services are back to normal.

While CCS did take steps following the Dec 26 problem that seemed to work during the Dec 28 and 30 enrolment periods we are investigating why the problem recurred this morning.

Please accept our apologies for the frustration and inconvenience this morning’s outage caused.

At 8:11 AM this morning (Dec 26, 2012) both the my.ryerson.ca portal and the CAS authentication service became unresponsive. CCS staff are investigating and we will update this alert when more information becomes available.

Update 9:08 AM: Service has been restored by restarting services for both the my.ryerson.ca portal and CAS authentication system. We are investigating the cause of the outage and can see that the service is still slow for some people.

Update 8:21 PM: As a preventative measure uPortal and CAS will be restarted at 6 AM on Dec. 28 and 30 and on Jan. 1 and 3. As a result there will be a brief outage of a few minutes after 6 AM on those mornings.

Update Dec. 27, 2012 at 12:37 PM: Preliminary investigations have shown that an SSL accelerator may have been overwhelmed by requests beginning at roughly 8:03 AM on Dec 26. A second SSL accelerator has been added in order to increase capacity. Additional CCS staff will monitor systems performance during the opening of the next RAMSS enrolment period.

Note: SSL (Secure Sockets Layer) is a protocol designed to securely encrypt information in transit on the Internet. The SSL accelerator is a network device that provides high-speed encryption/decryption services. It improves application performance by relieving servers of complex public key and bulk encryption tasks.

Please accept our apologies for this outage.
