University of Cambridge Computer Laboratory - Notice history

We observe that internet connectivity appears to be working again at the moment, though we have had no information yet from UIS so cannot guarantee that this will remain the case. The advice to work from home tomorrow still stands for now.

The Departmental Silver Team has decided to recommend that you work from home tomorrow if you can.

Partial connectivity (about 40%) has been restored as of 15:26.

This remains a University-wide problem but we have had no information from UIS yet.

If connecting from the internet into our network, only about 40% of our servers will be reachable. If you are unable to connect directly to the system you need, try going via CL VPN1, CL VPN2 or the UIS VPN. If connecting via SSH, you could try connecting via slogin or some other departmental server such as ely.

Internet connectivity in William Gates Building offices, as well as the rest of the University including eduroam, other departments and colleges, is likely to be barely usable.

Our main departmental website www.cst.cam.ac.uk remains accessible from the internet as it is hosted outside the University; however pages on www.cl.cam.ac.uk are affected.

We observe that the University is now completely offline. This situation is beyond our control and we await UIS to repair the fault.

We believe that (with the exception of the Robotics-CL and govroam networks, as previously mentioned) the wifi service has been fully restored. Please contact service-desk@cst.cam.ac.uk if you are still experiencing any issues. We regret the unexpected disruption.

Fixing the UniOfCam-Guest network will require us to withdraw the Robotics-CL and govroam networks which we believe not to be in use currently. The new software platform for our wifi infrastructure is unexpectedly limited to 6 networks (SSIDs). Please contact service-desk@cst.cam.ac.uk if you are relying on either Robotics-CL or govroam networks.

We believe wifi is fully operational again, except for UniOfCam-Guest. We continue to work with UIS on this.

As service starts to be restored, you may find that eduroam starts working before Internal-CL or wgb. If you are seeing our networks listed but are struggling to connect, try selecting eduroam.

Progress is being made towards a solution. We have implemented an emergency fix for two issues which unexpectedly caused UIS's new wifi setup to be incompatible with our existing departmental network configuration. We understand that UIS are still working on some other problems preventing wifi from functioning. We have no ETA at present for a resolution of those.

Wired ethernet connections are, as ever, available throughout the building upon request to service-desk@cst.cam.ac.uk.

Statement from UIS:

The work scheduled to take place this morning to migrate access points (APs) on the West Cambridge site is overrunning. We had hoped to complete the work between 06:00 and 09:00 but have unfortunately not been able to complete the work in this timeframe. We are working to complete as soon as we can and will update this message when complete. We're sorry for any inconvenience caused by this delay.
