The Badlock Bug

Following the disclosure of the Badlock vulnerability details, we have assessed the risk to University IT systems as being low. We will be patching all Windows servers maintained by CiCS, and all University managed and YoYo Desktop computers as part of our normal patching procedures. 

Please ensure that any servers, desktops or NAS drives you maintain are patched and have all updates applied. If you are unsure whether your system is affected by Badlock, please contact the vendor who will be able to provide you with more details.

Internet Outage (January 19) Report

At 11:21 on Tuesday 19 January the internet connection to the University failed. This left several important University IT services including MOLE and Google Apps inaccessible until our connection was restored at 16:35.

The internet outage affected the University of Sheffield, Sheffield Hallam University, and all the educational institutions in Yorkshire that receive their internet connection via the two Sheffield Universities.

Following the internet outage we had a debrief with JANet (the government funded HE network that provides our connections).

On Sunday 17 January monitoring systems run by the cable provider indicated a ‘low light’ fault causing significantly reduced performance on the back-up link connecting Sheffield Hallam University to the internet. The Hallam link serves as our own back-up internet link. Engineers were scheduled to locate and fix this fault for Tuesday the 19th of January and all internet traffic was diverted to our primary link. From this point onward our internet connection was entirely dependent on the primary link.

At 11:21, road excavations (a man with a jackhammer) severed the primary link and our internet connection was lost.

This double physical loss is a very unlikely event, but clearly our reliance on this connection is critical. We were already investigating the viability of alternative or additional solutions to mitigate against future loss of connectivity.  

This will take longer decide and plan for, and may require us to change the way some services are delivered. The nature of our plans will be communicated once we are clear what we are going to do.

Saving £100,000 a year with mobile contracts migration

Last year we agreed a new contract with O2 in an initiative that should save the University more than £100,000 a year. To help us reach this target, we are working with departments to coordinate the migration of old Vodafone or O2 connections to the new O2 tariffs. We will soon be getting in touch with the remaining departments to complete an audit of phone and tablet connections that need migrating or which may need disconnecting if they’re no longer used.

As well as saving a huge amount of money every year, the new arrangement with O2 means that all tariffs will include unlimited calls and texts. They will also be on 30-day rolling contracts, so they can be easily cancelled if they’re no longer needed, or changed to better suit your needs. For example, if you find you need more data than you originally thought, the allowance can be increased as quickly as the next month.


You may not need a new handset, but if you do, a new range of 4G-enabled phones is available to suit your work requirements and all work well with Google Apps. To look at the range of handsets and tariffs available, visit our mobiles page.
