What is a Freeze?
A production freeze ensures service availability and reduces risk by establishing a period of time—or "freeze"—during a business cycle where no major changes are made to services and systems.
Targeted freezes are specific to certain systems.
Requesting a Freeze
Event-related production freezes support campus wide or unit special events. Any U-M staff member may request a freeze for an event by submitting a request to inform ITS of a campus event.
Freeze dates are calculated based on the academic calendar published by the Office of the Registrar.
