We will be upgrading the University's network firewall infrastructure, including the firewalls that support both on‑campus internet access and connectivity to Microsoft Azure services.

During the maintenance window, users may experience a very brief interruption (lasting only a few seconds) to internet and Azure connectivity while services fail over during the upgrade process.

This essential maintenance forms part of our ongoing programme of security patching and service improvement, helping to ensure the network remains secure, reliable, and fully supported.

Any disruption is expected to be minimal, and services should reconnect automatically.
