    UIS (who operate our Wifi network and many others around Cambridge) have announced a major incident affecting University wireless services.

    New connections to eduroam, UniOfCam-Guest, UniOfCam-IoT and Internal-CL are currently failing. Established connections are working, but users are unable to establish new connections or are losing their connection when roaming.

    In the William Gates Building, as a temporary workaround, you can connect to the network named wgb. This is a lower-performance network intended for temporary visitors to the building, with connectivity provided through a commercial ISP (so you may also need to connect to the VPN to access internal University or Department systems). Please remember to switch back to Internal-CL or eduroam after the outage is over as wgb is less secure, slower and more expensive for us to operate.
