Regular maintenance windows are scheduled to facilitate the application of system patches and upgrades to the University IT infrastructure, in order that the central IT services may run under optimal conditions. Services, such as network, e-mail, web-sites, e-learning etc., are subject to short or long interruption during the period. While we try our best to minimise impact on users when scheduling maintenance, users are advised to avoid relying on affected services during the maintenance periods.
