Network Switch Software Maintenance: 2nd January - 5th January 2026



What is being done?
Network switches are having the latest software installed, in line with the switch manufacturers recommendations.

When is it being done?
The change window is 22:00 on Friday 2nd January until 06:00 on Monday, 5th January 2025.

Software updates are being installed between 22:00 and 06:00 each night.

Who will this affect?
The software update is being applied to all network ‘edge’ switches, so the university’s wired and wireless networks will experience a service interruption overnight. Data centres will be unaffected by this work.

How will this affect service users?
While the switches apply the new software, and reboot - network services will experience a 20-minute service interruption.

Why is it being done?
This is essential maintenance to ensure the network switches have the latest software version as requested by the manufacturer.
