Information Services acknowledge that users of IT resources in the University may wish to use systems and services at any time of the day or night, 365 days of the year. However, due to the need to replace equipment or upgrade software from time to time, in order to keep systems running, resolve problems, or improve services, there will be times when services are temporarily withdrawn.
When work is planned in advance and a large number of users will be affected, IS will normally advise users of the downtime they can expect (what service[s] will be affected, when, and for how long) via IS Service Messages, ISSUE, and the IS website.
However, there are occasions when the work has to be done as a matter of urgency, it is difficult to identify which users will be affected, or the impact of the downtime is small. The work will then be done during an At Risk period, without advance warning to users.
The At Risk periods are:
Monday - Friday 07:30 - 08:30
Sunday 08:00 - 13:00
