Sites Environment Freeze Information
Campus Computing Sites places a "freeze" on our software environment during the first and last months of each term. This ensures that our loadsets are in a stable condition during the high-usage period surrounding exams. We will not deploy new software or make loadset changes during this time.
What is a freeze?
A freeze is a time when staff limit changes to the environment. This is to both maximize stability during critical times of the year and to make staff available to quickly address issues that may arise during these times. We wish to limit the risk of outages and maximize staff availability when they occur.
When are freezes?
- Fall Term: The first 2 weeks of classes and the last week of classes.
- Winter Term: The first week of classes and the last week of classes.
- Spring/Summer Term: No specific freeze period. General policy is to make no major environment changes during exam periods and only make core software upgrades between term breaks.
These are in addition to ITS Production Freezes.

- No switch deployments or network upgrades.
