Mosaic will undergo three scheduled weekend outages between March and June as part of our planned efforts to improve the system and enhance your experience.
These upgrades will introduce a more intuitive interface with improved navigation, updated page headers and a stronger search experience. Learn more about the changes coming to Mosaic.
Outage 1 — Friday, March 13 at 5:00 p.m. to Monday, March 16 at 8:00 a.m.
Mosaic will be unavailable during this outage. After this outage, users will begin to see updates to the system’s design and layout.
Outage 2 — Friday, April 10 at 5:00 p.m. to Monday, April 13 at 8:00 a.m.
This will be a partial outage affecting HR functions. Other areas of Mosaic, including student-related tools, will remain available.
Outage 3 — Friday, June 5 at 5:00 p.m. to Monday, June 8 at 8:00 a.m.
This will be a partial outage affecting Finance functions. All other Mosaic functionality will remain available.
University Technology Services (UTS) consulted with various campus partners, including the Registrar’s Office, Human Resources, Financial Affairs, and others, to decide on the planned outage dates with a goal to limit impact to the campus community.
Students, staff and faculty are encouraged to complete any time-sensitive tasks before or after these outage windows. Live updates for each outage will be posted on the McMaster Service Status Page.
These planned outages support important upgrades that will improve Mosaic’s usability, reliability and overall experience for everyone who uses the system.
