    One of the two affected circuits (one of two from the WGB to the University Data Network) has been successfully diverted and brought back up. The other affected circuit (one of two connecting the two halves of internal our network in WGB and the West Cambridge Data Centre) will be migrated around 11:15. Again, no disruption is expected.

    UIS need to divert two of the fibre circuits connecting the William Gates Building to the West Cambridge Data Centre and to the University Data Network. No disruption is expected as traffic will automatically use alternate paths, but we will be operating with no redundancy for two 10-15 minute periods during 6th February and networking should be considered at risk.
