Hi Felix, William,

University IT are planning two major upgrades of the key firewall 
devices protecting the University’s network on Sundays 18^th of November 
and 9^th of December.

The change on the 18^th will mostly affect desktops, printing, Wi-Fi, 
building management and access to the internet, whereas the change on 
the 9^th will affect these/and/applications hosted in the University’s 
data centres.

The team running the project has convened a working group for the 
changes to work through all the IT testing required on each of the days, 
however we are also asking key business/student areas and affiliates who 
use the UWA network to also consider any testing they may need to do.

As a rule of thumb, we are asking these areas to test Wi-Fi access, 
logon/logoff, internet access and printing just to make sure these have 
returned to normal after each change, and for the 9^th Dec to check any 
of their key UWA hosted applications as well. Uni IT and the Service 
Delivery Centre (SDC) IT teams will also be performing testing.

**

*It’s my understanding that UCC has some network devices using IPv6 and 
this network will also be moved to the new firewalls. We recommend you 
test these either on Sunday 18^th between 10AM and 12PM if you have any 
critical IPv6 devices in use, or on the following Monday. *If you do 
plan on testing on the Sunday, I’ll just need to get some further 
details off you so we can add you to the list of people being 
communicated to on the day.

Plans are already in place for notifications of these changes to be 
placed in UWA Forward, student newsletter and social media.

If you have any questions, would like to be involved in the working 
group or just to be kept informed, please let me know. Further details 
below that can also be used for wider comms if needed.
