ITS Scheduled Maintenance 2019

We carry out regular maintenance on the University's IT environment, such as deploying new enhancements and applying patches to fix known problems.  With the IT environment ever growing and becoming more complex, finding suitable time slots for maintenance works has become increasingly difficult.

The central IT services may be interrupted during these periods.  Departments are advised to avoid having critical events/activities, which rely heavily on the availability of central IT services, during the maintenance windows.

As not all maintenance works can fit into the scheduled windows and there are needs for urgent maintenance pop up every now and then, we do expect some maintenance activities will be carried out outside the scheduled maintenance windows.  We will notify users concerned via the appropriate channels when such needs arise.
