Major maintenance is work that will require servers or services to be down for several hours in order to do work such as patching and upgrades.  The exact times of expected service outages will be announced at least 3 days prior to the major maintenance window.  These times will reflect our expectation of how long it will take to do the work, but should typically be between 9am and 1pm Saturday and also 9am to 1pm Sunday (if needed).

Additionally, there will be periods of time between semesters where Infrastructure will apply upgrades and changes to services during the work week in preparation for the next semester.  These weeks, sometimes called "High Change" weeks are as follows:

Fall: Aug 13 - Aug 17
Spring: Dec 27 - Jan 4
Summer: May 27 - May 31

Dates near Finals weeks are considered "Low Change" periods and are times where no major changes to services will be made and all maintenance will be delayed where possible and pushed to maintenance windows otherwise.  Infrastructure's "Low Change" dates, which are similar toTechnology Services'  "No Change" periods but do not match exactly, are as follows:

Fall 2015: December 10th - December 23rd
Spring 2016: May 5th - May 20th
Summer 2016: August 4th - August 12th
