CLASSE Computing Outages: 03-Aug-2026 to 08-Aug-2026

From Monday, 03-Aug-2026, to Saturday, 08-Aug-2026, various CLASSE computing services both onsite and offsite will be disrupted by a series of scheduled power outages due to electrical maintenance at Wilson Lab. The main outage will begin on Thursday, 06-Aug-2026. Please note that, although Wilson Lab will regain power around 12:00 noon on Thursday, 06-Aug-2026, we do not expect to have most CLASSE-IT services restored until Saturday, 08-Aug-2026. Additional recovery efforts might extend farther into the weekend. For a full schedule of impacts, please see this page (CLASSE login required).

General network and server maintenance will occur every Tuesday from 12:00 noon to 2:00 PM. The CLASSE-IT group will always announce any expected disruptions in our NewsLetter and via CLASSE-IT-NEWS-L, but with the size and complexity of our network there is always the potential for something to go wrong. We will do our best to contain all network maintenance and planned outages to Tuesdays from 12:00 noon to 2:00 PM.

Unless other arrangements have been made, CLASSE-managed Windows systems may be updated and rebooted on Tuesday morning at 2:00 AM, so please avoid critical or lengthy operations at that time. For more details, please see SystemExpectations.

The BeamPASS application receives bug fixes and new features on Tuesdays. When these updates are made, users will be logged out but should be able to login again within a few minutes. If you find BeamPASS is unavailable for longer than that, please submit a ServiceRequest.
