We will be doing work on our email servers which should not affect customers. The work involves rebuilding one of the two back end file stores and will be taking place across multiple days.
This work has been moved to next week - week beginning 20th January.
Due in 3½ days
The work outlined below will start from Saturday 23rd November.
Background:Our FireBrick team has been working on the 'hang' problem that we faced with the LNSs earlier in the year.
The nature of the problem has made investigating the problem very time consuming as it is extremely difficult to reproduce. However, we do believe that a plausible cause has been identified, and code changes have been made to mitigate the problem.
We have been testing this new code, both in our test lab and on a few select A&A routers, for over two months. During this time the new code has not caused the hardware to hang, where older versions of the code did.
Our next step is to run the new code on our LNSs, the ones our customers connect to for their broadband connections.
We plan to do this slowly, out of hours and in a couple of phases.
We believe the cause of the hang is related to how memory is initially allocated for the tasks the FireBrick will be performing, this means that if the hardware is going to hang then this will most likely happen over the first couple of days (or first couple of hours).
Stage one: (Completed)
We plan to upgrade only one of our LNSs at first. We will move broadband connections on to it in the early hours of the morning and then move them back off a few hours later. This means that during the day, customers will be on the normal set of LNSs.
Then, each night, over the course of two weeks, the LNS will be power cycled and we will move an increasing number of connections over, until it is at the point of taking twice the amount of connections that we'd normally run on an LNS. (We normally run LNSs at around 40% capacity, so twice the number of connections is not a problem.)
Stage two: (Completed)
Once we have confirmed that the hang is not happening, the second phase would be to run customer connections on the upgraded for a few days at a time.
We will go through a cycle of: move connections off, reboot the LNS, move connections on, wait a few days. Repeat. We will do this with an increasing number of connections until it's at the point of taking a normal amount of connections.
Stage Three:
As of the end of 2024, half our LNSs have been running the new software without any problems. From January 7th we will e doing overnight upgrades of the remaining LNSs.
More information:
So as to minimise impact to customers, the work of moving connections off and on will happen overnight between 1AM and 5AM.
Overnight test over the weekend have so far been successful. We'll be continue to test during his week.
No problems thus far. We are now at phase 2, where we are running customers on the upgraded LNS for longer periods of time. We currently have eight LNSs in use, and one (i.gormless) is running the new software. This stage will involve lines on G, H and I.Gormless.
Still no problems. We will upgrade two more LNS (G.gormless and H.Gormless), and will move some customers on to these over the weekend. This will happen overnight.
All LNSs remain stable. Over this weekend (14-15th December) we will upgrade further LNSs and move customers between LNSs: E, F, G, H, I. This will be our last set of LNS upgrades until the new year.
These LNSs are now running newer software: F, G, H, I. We'll continue this work in the new year.
Overnight works are planned to upgrade the remaining LNSs. This will happen from 8th January onwards.
All of our LNS routers have been upgraded and all are working well. We will continue to upgrade our remaining FB9000 BGP routers over the next 10 nights.

This is only relevant to customers who run their own authoritative DNS servers and use our secondary-dns.co.uk as an additional nameserver.
Overview: We run a "secondary" DNS service for customers where they run the master DNS server and we are secondary slaves. We have a project underway that involves migrating all our authoritative DNS services to a new platform. As part of this we are needing to disable some of the automation we do for adding and updating the customer's master IP address automatically.
The change: From June 17th, If you run your own master DNS server for your domain(s) and secondary-dns.co.uk is a slave, if you change the IP address of your master you will need to contact support@aa.net.uk to request us to update our side.We have more information about our Authoritative DNS project on our Support Site: https://support.aa.net.uk/New_Authoritive_DNS
This change has been made.

This will search through the various outages and maintenance reports we have received from our suppliers which may be affecting you.
You can also see a list of outages and maintenance work we receive from our suppliers that may affect your specific broadband service on the Control Pages.
The search box above should find posts affecting your service however, you can use a Keyword search.
This is the status page of Andrews & Arnold Ltd.
Our status page shows outages (problems) and maintenance (planned work) that happen on our own network and systems and also that of our suppliers networks and systems. We try and ensure this site is updated as soon as possible with incidents as they happen. Live discussion of issues is usually available on IRC.
