We have work planned for the early hours of Friday morning that entails upgrading software on our LNSs and moving CityFibre and higher-speed BT/TalkTalk services on to separate pools of routers (LNSs) at our side.
In practice this will mean that most customers with speeds of 80Mb/s and above will experience a few PPP drops and reconnects between 3AM and 5AM as we carry out the work.
This is related to the hardware hangs we've been experiencing: https://aastatus.net/42608 and it will help us further investigate this ongoing issue.
During the early hours of Saturday 16th and Sunday 17th we will be performing some software upgrades and rebalancing of customers that are currently on the A, B, C, G, Y, Z LNSs.
The aim here is upgrade the software on some of them and to spread the customers a bit more evenly over them. Customers on X will remain as is.This week we have installed three additional FB9000 LNSs. These are: A.Gormless, B.Gormless, C.Gormless. These are in addition to the existing: G.Gormless, X.Witless, Y.Witless Z.Witless which are all used for customers on faster circuits (80M and above).
As of Friday 9th customers (with 80M and above connections) are mostly connected to G, X, and Y.
During the early hours of Saturday 10th and Sunday 11th we will rebalance customers that are currently on G and Y over to A, B, C, G, Y, Z - the aim here is to spread the load so fewer customers are on each LNS which means fewer customers will be affected if the LNS locks-up. Customer on X will remain as is.
We will be making live a new LNS called "G.Gormless" and adding it to the pool of LNS for our faster lines. This will complement the existing X, Y & Z Witless LNSs.
