Engineering work will be undertaking an essential software upgrade within the resilient virtual firewall infrastructure at the London 3 data centre. This work will allow further virtual firewalls to be provisioned whilst also removing a software bug recently identified that is preventing provisioning activites to take place. This work has been recommended by the vendor.
No customer impact is anticipated during the works as virtual services hosted on the device being worked upon will be migrated on to unaffected resilient devices within London 2. However, there is a very slight possibility of disruption to services in London 3, mainly the DNS platform but also including DSL and Leased Lines.
