DuckWeb will be unavailable this entire weekend while Information Services performs essential maintenance.

This round of behind-the-scenes work is expected to take longer than usual, starting at 7 p.m. Friday, May 31, and lasting possibly as late as 10 p.m. Sunday, June 2.

DuckWeb is the website University of Oregon students, faculty members and staff use to check grades, view pay stubs and change personal information.

During the maintenance, several related administrative applications also will be unavailable: Banner, the behind-the-scenes side of DuckWeb; AppWorx, a job scheduling service; DuckDocs (OnBase), a document management and electronic workflow service; and Integrated Data and Reporting (Cognos), a reporting and analytics 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.
