Welcome to Network Services

The UIS network team provides a variety of wired, wireless and other network services for use by staff, students and institutions around the University. These include the Cambridge University Data Network (CUDN) and the Granta Backbone Network (GBN).

Here you will find information about all these network services, including any charges and associated technical information for IT staff.

The information is separated into two areas:


Information for Staff and Students

This area contains general information about using the network services, which supplements help and support provided by the UIS Service Desk.


Information for Institutions and IT Staff

This area contains information about running, managing or understanding the network services. It includes service charges and technical information. The material is written for institutional managers and IT staff.

If you have any enquiries regarding UIS network services, or other University network topics, please send an email to:
