ICT Maintenance Windows
Information and Communications Technology schedules maintenance windows to perform regular work on its infrastructures. This comprises of network, servers, workstations and software services. Regular maintenance is important to ensure that software and infrastructure is properly patched, and changes to provide better services can be implemented on a timely basis.
There are three types of scheduled maintenance windows: Workstation Maintenance Windows, Minor ICT maintenance windows and Major ICT maintenance windows, and each are discussed in the following sections.
Workstation Maintenance Windows
Regular workstation maintenance windows, occur Wednesday night between 10pm - 3am (5 hours), though your machine will only reboot in order to apply patches or application updates as required. This ensures that your computer has the best protection from cyber-attacks or other software vulnerabilities, identified by vendors or agencies such as AUSCERT.
Laptops that are off campus at the time of the maintenance window, will still reboot if they have pending updates.
ICT also offers an “in hours” maintenance window Wednesday 11am - 4pm weekly (5 hours) for systems that require staff onsite to restart processes after a system restart. Please contact the IT Helpdesk, if you have a workstation that needs to be included in the “in hours” maintenance window.
Minor ICT Maintenance Windows
Minor ICT Maintenance Windows are regular publicly advertised time slots which allow the implementation of changes that will impact services. There are two (2) minor maintenance windows scheduled each week; one on a Wednesday evening (8 pm to 2 am AEST Thursday); the second on a Sunday (6 am to 10 am AEST).
All scheduled service outages are notified via ICT Bulletins.
The Minor ICT maintenance windows are used for regular computing and communications upgrades and maintenance. Where possible, any scheduled upgrades and/or maintenance of ICT computing and communications infrastructure requiring service shutdown or restart, will be scheduled during these maintenance windows.
Major ICT Maintenance Windows
Major ICT Maintenance Windows occur once every six (6) months, as listed in Table 1 schedule below, are weekends (from 7pm Friday to 11pm Sunday AEST) when the entire JCU network - and all services - will be unavailable to allow upgrades to be performed.
Note: These will be server and/or network upgrades - not application upgrades. These scheduled outages are notified in advance via ICT Bulletins.
These major ICT maintenance windows should be taken into account when planning any University event that requires any computing and/or networking services on-campus, including video conferencing.
These weekends were chosen after extensive consultation with the University community to avoid study periods one and two, as well as taking into account constraints such as:
Study period census dates
Subject result release dates
QTAC offer dates
The overall criterion we were adhering to in selecting these dates was to minimize impact on academic activities.
The major ICT maintenance window dates are as follows:
5 - 7 July 2019
6 - 8 December 2019
