Editor's note: The Active Directory downtime July 19-20, as described below, has now been confirmed by Information Services.

Several critical technology services at the University of Oregon will experience extended downtime or other potential impacts while Information Services continues its data center infrastructure upgrade.

The Duck ID Account Management website will be unavailable twice within one week. The first time will be for two hours on Wednesday, July 12, from 10 a.m. to noon. The second will be for at least 12 hours, from Friday, July 14, at 7 p.m. to Saturday, July 15, at 7 a.m., and possibly longer.

Several other services will also be unavailable for up to 18 hours overnight, from Friday, July 14, at 7 p.m. to Saturday, July 15 at 1 p.m. Those services include DuckWeb, the Degree Guide website, Banner, AppWorx, DuckDocs (OnBase) and Integrated Data and Reporting (Cognos).

Finally, a critical back-end service known as Active Directory is scheduled to move to the new infrastructure starting Wednesday, July 19, at 6 p.m., pending final internal approvals in Information Services. If any service interruptions occur, they're expected to be minor.

However, this work has the potential to cause broad disruptions to dozens of UO services that rely on Active Directory, from computer logins to email flow and UO VPN. Those disruptions could last up to 14 hours, until 8 a.m. on Thursday, July 20.

Details about upcoming service outages will be posted on the IT Service Status website. That's also where Information Services will post updates if maintenance schedules change, along with in-the-moment updates if the work runs long or causes unexpected problems.

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