We operate multiple LNSs connected to multiple links in to carriers. This is partly for redundancy (if one of the LNSs or links break) and partly for load (to handle multiple gigabits of traffic).

We currently have 14 LNSs in use (A-N), plus one spare and one 'test' LNS. This has grown over time with four in 2012, seven in April 2016, nine in January 2017, twelve in November 2017 and 14 in September 2018.
We currently have 22 FireBrick FB6000 LNSs in use (A-V.Gormless), 3 FireBrick FB9000 LNS (X-Z.Witless). This has grown over time with four in 2012, seven in April 2016, nine in January 2017, twelve in November 2017, 14 in September 2018.

The LNSs named 'Witless' handle faster FTTP and G.Fast circuits, whilst the 'Gormless' LNS handle the rest, including mobile data SIMs.


Normally we run with n-1 live LNSs and so this leaves one as a backup in case of failure.
