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 for 24 hours this weekend while Information Services performs essential maintenance.

The work is scheduled from 7 p.m. Friday, May 6, to 7 p.m. Saturday, May 7.

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.
