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 this website - https://www.its.hku.hk/maintenance/schedule. 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.
Note:
- The maintenance window in January 2020 is postponed for a week until end of the online assessment schedule of the first semester.
