ITS Scheduled Maintenance 2021

ITS carries out regular maintenance of the University’s central IT environment generally in the first weekend of each month, from Saturday 1:00 pm to Sunday 11:00 pm.  The monthly maintenance windows in 2021 are scheduled as follows:

On top of the above maintenance windows, 4 additional timeslots are scheduled in the following weekends in 2021 for coping with the increasing number of systems in operation:

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.
