The Libraries IT Division has scheduled an upgrade of the Sierra operating system for Wednesday, March 15 beginning at 5:00 pm. This will require approximately six hours of downtime for both Sierra and the library catalog. We chose the date because it occurs during Spring Break when the number of people affected by the downtime will be diminished. By scheduling it in the evening, it is less likely that staff workflow will be disrupted.

As the operating system is upgraded, we don’t expect the system to be down for more than six hours, but we will send out an update to staff should that time be extended for any reason.
