my.ryerson portal extended outage: Friday Nov. 14, 2014

Posted on November 14, 2014 by Casey Carvalho

This morning, between 6AM – 8AM, the my.ryerson portal was taken down as part of scheduled work to allow for a redesign of the portal.   Unfortunately, some unexpected issues delaying the completion of the work.   Services were restored at 8:50AM.   Unfortunately, other issues were detected and services are currently unavailable.   We will provide an update shortly.

9:30 AM -Update- We are restoring my.ryerson portal to the previous version.  We expect it to be available by 11:00 AM today.

Update: The previous version of the portal was restored and made available around 11:05AM.

Update: The cause of the problems with this morning’s my.ryerson.ca redesign update have been identified. The portal software keeps track of everyone’s page layout in its database. When we made changes to the design this morning the software attempted to update thousands of database entries for each person’s page layout. Instead of a brief slowdown, the result was a “deadlock” on some database tables. Consequently we rolled back the upgrade and are investigating ways to update the portal database safely.

 

Please accept our apologies for any inconvenience.

Mail delivery delay: Tuesday, Nov. 4, 2014, 11:00 AM – 3:20 PM

Posted on November 5, 2014 by Hongbo HE

Starting around 11:00 AM, Nov. 4th, our email system experienced delivery delays of up to 15 minutes. These delays are due to an incorrectly configured mailing list that was replied-to numerous times and generated over a hundred thousand messages during a short period of time. We put these messages on a lower priority queue and released them gradually. At 3:20 PM, the mail delivery time was returned to normal. CCS staff continue to investigate ways to mitigate issues like this.

We apologize for the inconvenience.
