Please note that we will need to take ROSI and most associated student information systems offline on Friday, August 18 from 5 p.m. to 9 p.m. to perform quarterly maintenance on the database. We will return the systems to service sooner if the work is completed earlier than 9 p.m.

In addition, while ROSI-REPLICA on MI will remain accessible during the maintenance, data will not be synced with ROSI starting at 5 p.m. It will be synced again at 9 p.m. when maintenance is complete.

The following systems will be affected:

• Accommodated Testing Services (Student and Admin)
• ACORN
• Course Information System
• Degree Explorer (Student and Admin)
• EASI Institutional File Transfer
• Elections
• eMarks
• Online Administrative Student Information System (OASIS)
• ROSI
• ROSI Express
• ROSI Files
• Safety Abroad Student Registry
• Timetable Builder (Admin)
• Varsity Blues Registration System
• Web services/APIs

Timetable Builder (Student) will remain available.

A notice will be posted on the ACORN launchpad and social media so that students are aware of the outage. Note: the launchpad itself also requires maintenance. It will be unavailable for a maximum of 15 minutes during the larger maintenance period.
