We will be performing software upgrades on various FireBrick routers and LNSs across our network, starting this week. These are scheduled to happen between 1AM and 4AM and will happen over the course of a few weeks. With our LNS upgrades, we perform one upgrade night and will involve a line drop and reconnect of broadband lines for those connected to that particular LNS. This 'one LNS upgrade per night' will last until February 2nd.
We are half way through the LNS software upgrades, all going well so far.
