We are starting to roll out new software to the (non-LNS) FireBrick routers on our network. These will happen overnight this week, starting on 15th November. There should be no impact on customer services.
We are performing overnight software upgrades on our "Gormless" set of LNSs. This will cause customer lines to drop and reconnect when the LNS they are on is updated. We will be doing one LNS a night and the work starts from 1AM. Due to the number of LNSs this will last a few weeks. More information about LNS switchovers, and to control the time your line is forced to reconnect, please see: https://support.aa.net.uk/LNS_Switches
