Scheduled - CCS will run Tier 1 Maintenance of the Web Access Management/Single Sign On (WAM/SSO) service this Sunday June 10th between 12 AM and 12 PM.

We have been working with the vendor and resolved the root cause of the issue we encountered last Saturday. At that time we had to roll back all changes in order to bring the dependent services back before the end of the scheduled maintenance window.

While we will strive to keep the selected WAM/SSO-protected services, e.g., Gryph Mail and CourseLink, available throughout this maintenance they may become unavailable during some stages of the maintenance. We will evaluate the impact continuously and take corrective steps. The rest of the services dependent on WAM/SSO , e.g., departmental webservers, will be unavailable throughout the maintenance.

If you have any questions or comments about this maintenance please contact the CCS Information Security team via 58888help@uoguelph.ca.

The maintenance progress will be communicated via the CCS System Status Page at http://uoguelph.statuspage.io.

======
Details:

During these maintenances we will upgrade the Web Access Management/Single Sign On service.

We expect limited impact on the following SSO-protected services (possible intermittent downtime) close to the beginning and end of the maintenance window:
- CourseLink and Gryph Mail Office 365
- Federated Web SSO and the dependent services, e.g., Gryph Mail/GSuite, OpenEd/DestinyOne, GryphForms, GryphonsTickets, Pension Portal, Software Distribution, GryphLife, Gartner, Lynda, Qualtrics, Tableau, TeamDynamix, Kountu, various Library services; Off-Campus Access, Course Reserve, Primo, ProQuest, Webex, ExperienceGuelph.
- SSO protected websites behind www.uoguelph.ca, intranet.uoguelph.ca, www.housing.uoguelph.ca, and news.uoguelph.ca

Other WAM/SSO protected services including, for example, FRS, ECS, web tier for ImageNow, OpenEd Grade portal, Hospitality applications, WAM/SSO protected departmental webservers will be unavailable from about midnight until the noon.
