DuckWeb — the website University of Oregon students, faculty members and staff use to check grades, view pay stubs and change personal information — will be unavailable starting Friday, Dec. 17, at 7 p.m. while Information Services performs essential maintenance.

The work is scheduled to be completed by noon on Saturday. During that time, two related administrative applications also will be unavailable: Banner, the behind-the-scenes side of DuckWeb, and AppWorx, a job scheduling service.

Anyone with questions can contact the Technology Service Desk by phone at 541-346-4357, by live chat or through the UO Service Portal.
