At 3:05 am every morning the server will be unavailable for approximately fifteen minutes during our daily back-up procedures.
In addition, the hours between 5:00 pm and 8:00 pm on Friday evenings are always reserved for system maintenance. Most of the time this maintenance will not affect use of the system by students and instructors, but occasionally there will be a temporary outage during that period.
These interruptions apply to everything hosted on the server, including the CATE and Moodle courseware management systems and all classes in both those systems.
Please plan your online schedule accordingly.
