During these periods, certain central IT services/systems could be closed or intermittently unavailable.  We will announce the specific services/systems affected prior to each maintenance window via e-Notice and the website – Maintenance Notices.  Departments are advised to avoid having critical events/activities that would rely heavily on the availability of central IT services during the maintenance windows.

For urgent situations, ITS may be required to carry out system maintenance/repair works outside the regular schedules.  We will notify the users concerned via the appropriate communication channels under such circumstances.
