ITCS Production Freezes
What Is a Freeze?
During a freeze, no major changes are made to ITCS services and systems.
Security patches, critical updates, and emergency maintenance can be done during a freeze; manager approval should be obtained if at all possible.
Other changes can occur only with manager approval. Some exceptions require customer approval. Exceptions can be made for units with special/different needs. (For example, Campus Computing Sites sets freeze dates for sites on the Medical Campus in concert with the Medical School's different term dates.)
When Sites is in a freeze and the rest of ITCS is not, the rest of ITCS is aware of the need to minimize changes that could impact Sites.
