VPCIO Change Freeze Dates and Definitions

Objectives

At the start of the Fall and Spring semester and for several national holidays a VPCIO-wide system freeze period has been instituted for our production services.  During the freeze period VPCIO will not apply changes, modifications or enhancements to our production software applications and the hardware infrastructure that supports the applications used by student, faculty and staff.  The goal of the freeze period is to maximize the availability and stability of our services during peak usage periods or when staff availability is limited, thus the need to reduce the risk of problems being introduced by even the most routine maintenance/changes. 

Any exceptions for emergency changes during this time require VPCIO Director approval.

Definitions

  • Semester start up - the period of time just before students arrive through the first week of classes for the Fall and Spring semesters.
  • Production systems - any system that provides services for which there is an expectation of continuity.

Semester Startup Freeze time periods:

The semester start up freeze period is set using the following methodology for the Fall and Spring semesters:

  • Freeze Begins: 12:01 a.m. on the Thursday before the first day of classes. 
  • Freeze Ends: 4:30 a.m. on the first business day 1 week after the first day of classes.  Many times this will be a Tuesday due to Monday holidays.
