Google Calendar Access Disruption – December 10, 2014

CCS has received reports of users experiencing errors when accessing Google Calendar.  Typically, the message indicates that you need to log in and re-authenticate.

CCS is investigating and has contacted Google.  We will update this alert when we have further information. In the mean time, you may find that logging in again to the my.ryerson.ca portal temporarily resolves the problem with Google Calendar.

Update 4 PM: The issue has not been resolved but we have a little more information:

  1. “Users started experiencing the problem around 5 pm last night.
  2. If someone is logged into multiple Google accounts (e.g. @ryerson.ca account and a consumer Gmail account) on the same Chrome browser, they can be quickly booted out.
  3. If a user has cleared their cookies, and re-logs into their @ryerson.caaccount, they can be booted out after 1 hour.
  4. If a user is prompted with the “New” Google Calendar feature, and clicks the “OK, got it” button, the issue appears to be resolved.” (Note. This does not work for everyone.)

Update 10:00 PM, Dec. 12:  While we are still waiting for an official response from Google, we have implemented an interim solution so users won’t be asked constantly to log in again in order to access Google Calendar.

We apologize for the inconvenience,

– Computing and Communications Services

Please accept our apologies for any inconvenience this have caused.

Update 10:50 PM: The delay started at 6:48 PM and was due to emails sent to a mail list with very large number of members. CCS staff continue to investigate.

Update Wed.

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

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

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.
