We are seeing some evening time congestion on all BT 21CN lines that connect through BRAS's 21CN-BRAS-RED1-MR-DH up to 21CN-BRAS-RED13-MR-DH I suspect one of the BT nodes is hitting limits some evenings as we don't see the higher latency every night. This has been reported into BT and we will update this past as soon as they respond back.

The changes BT made over night have made a significant difference to the latency, still seeing it slightly higher than we would like so we will go back to then again.

BT have advised that they are aware of the congestion issue at Manchester, and the solution they have in place is to install some additional edge routers, they are already escalating on this to bring the date in early, currently the date is May. Obviously May is just not acceptable and we are doing all we can to get BT to bring this date forward.

We have requested a further escalation within BT, the time scales they have given for a fix is just not acceptable.

Over the past couple of weeks we have seen FTTC lines drop and reconnect with in increase in latency of around 15ms. This is seen on the monitoring graphs as a thicker blue line.

Upon first glance it looks as if interleaving has been enabled, but a line test shows that this is not the case.

We've been in contact with BT and it does look like BT are rolling out a new profile on to their Huawei DSLAMs in the local green cabinets. It has been expected that BT would be rolling out this new profile, but we didn't expect such an increase in latency.

The profile adds 'Physical Retransmission (ReTX) technology (G.INP / ITU G.998.4)' which helps with spikes of electromagnetic interference and can make lines more stable.

We would hope to have control over the enabling and disabling of this profile, but we don't. Line profiles with FTTC is managed by BT Openreach and are tricky for us and even BT Wholesale to get adjusted.

We're still discussing this with BT and will update this post with news as we have it.

Some customers connected through Gloucestershire are affected by an ongoing TalkTalk major service outage. Details below: Summary

Network monitoring initially identified total loss of service to all customers connected to 2 exchanges in the Gloucester area. Our NOC engineers re-routed impacted traffic whilst virgin media engineers carried out preliminary investigations. Virgin media restoration work subsequently resulted in several major circuits in the Gloucester area to fail.

This has resulted in a variety of issues for multiple customers connected to multiple exchanges. Our NOC engineers have completed re-routing procedures to restore service for some customers with other customers continuing to experience total loss of service due to capacity limitations. Impact: Tigworth, Witcombe and Painswick exchanges

Hardwicke and Barnwood exchanges – experiencing congestion related issues.

Cheltenham and Churchdown – experiencing congestion related issues.

experiencing congestion related issues Stroud, Stonehouse, Whitecroft, Blakeney, Lydney, Bishops Cleeve, Winchcombe, Tewkesbury, Bredon exchanges.

TT have advised that splicing of the affected fibre is still ongoing. There is no further progressive updates at this time. Further updates will be sent out shortly.
Update
2 Apr 11:57:26
Root cause analysis identified a major Virgin Media fibre break due to third party contractor damage as being the cause of this incident. Service was fully restored when Virgin Media Fibre engineers spliced new fibre. Following this we received confirmation that service had returned as BAU. TalkTalk customers would have been automatically rerouted and would have experienced only a momentary Loss of Service. An observation period has been carried out verifying network stability and as no further issues have been reported this incident will be closed with further investigations into the cause being tracked via the Problem Management process

TalkTalk say they have fixed this. We'll be checking overnight to be sure smiley
Update
26 Mar 22:27:33
Lines are looking good.
Resolution

We had this feedback from TalkTalk regarding this congestion issue:

Shepherds Bush has three GigE backhauls to two different BNG's - there was some a software process failure and restart on one of these devices on Tuesday morning which had two of the three backhauls homed to it. As a result all customers redialled to the one 'working' BNG in the exchange - normally when this happens we will calculate whether or not the backhaul can handle that number of customers and if not manually intervene, in this case however a secondary knock on issue meant that our DHCP based customers (FTTC subs) were sent through the same backhaul and the calculation was inaccurate.

If the PPP session was restarted they would have reconnected on their normal BNG and everything should be OK - we've just made this change manually moving subscribers over - still have a couple of lines on the backup BNG so will monitor if there are any issues and take any necessary actions to resolve.

Many of our customer broadband lines suffered a blip just after 2am. We're still investigating that, but it seems our RADIUS accounting got behind due to the high number of lines flapping. It looks like accounting has caught up now, but it will mean that we sent out some delayed notifications over night. This could result in, for example, line down/up notification emails delayed by several hours. The time stamp in the notification should show if this is the case.

We currently supply the Technicolor TG582 for most ADSL services, but we are considering switching to a new router, the ZyXEL VMG1312-B

It is very comprehensive and does both ADSL and VDSL as well as bridging and wifi. It means we can have one router for all service types. As some of you may know, BT will be changing FTTC to be "wires only" next year, and so a VDSL router will be needed.

We have a small number available now for people to trial - we want to test the routers, our "standard config" and the provisioning process.

Please contact trial@aa.net.uk or #trial on the irc server for more information.

P.S. Obviously it does Internet Protocol, the current one, IPv6 and the old one IPv4

Obviously this initial trial is limited number of routers which we are sending out at no charge to try different scenarios. However, we expect to be shipping these as standard later in the month, and they will be available to purchase on the web site.

Update

Thanks for all the emails and IRC messages about trialling the new routers. We will contact customers back on Monday to arrange shipping of the units.

The Technicolor routers we supply have a factory default config which connects to us and operates a default setup. This is applied if someone uses the RESET button on the routers.

We have identified that a few dozen of these routers are in this state, which is not correct.

As part of work we are doing for some new routers we plan to start shipping soon, we have made it that any router logging in using the factory default will automatically be updated to have the correct config.

This will likely cause the graph to reset and the LNS in use depends on the login, but it will also set the WiFi SSID correctly, and other parameters. So users may see a change.

If you have any issues, do contact support.

Resolution The change in process has meant a number of routers have been auto-provisioned as expected, the remainder will when they next connect. Any issues, do contact support.

In addition to all of the BT issues we have ongoing (and affecting all ISPs), we have seen some signs of congestion in the evening last night - this is due to planned switch upgrade work this morning. Normally we aim not to be the bottleneck, as you know, but we have moved customers on to half of our infrastructure to facilitate the switch change, and this puts us right on the limit for capacity at peak times. Over the next few nights we will be redistributing customers back on to the normal arrangement of three LNSs with one hot spare, and this will address the issue. Hopefully we have enough capacity freed up to avoid the issue tonight. Sorry for any inconvenience. Longer term we have more LNSs planned as we expand anyway.
Update
24 Jan 07:30:14
The congestion was worse last night, and the first stage of moving customers back to correct LNSs was done over night. We are completing this now (Saturday morning) to ensure no problems this evening.
Resolution Lines all moved to correct LNS so there should be no issues tonight.

Update from TT. Summary Network monitoring has identified that Wholesale Business customers across the country may have experienced a brief loss of service between 14:00 and 14:05. Network Monitoring completed by our NOC has identified that there was a drop of traffic at these times between a Network Core Router at the Brentford Data Centre (NCR002.BRE) and a Redback router (LTS001.HEX). This subsequently caused Wholesale Business customers who route through Harbour exchange to experience a loss of service.
Resolution Technical / Suspected Root Cause Investigations by our Network Support have identified that this issue occurred due to planned LTS work under SR8753. This work caused the queues on the LTS to fill up and caused a CPU spike, which in turn caused the tunnels to drop. There are plans to increase circuit capacity going forward to ease bandwidth levels and prevent a repeat of this issue.

We may have to restart one or two of our LNSs in the early hours of Monday morning as there seems to be an issue with them. This is not affecting service at present but does mean we do not have any of the normal graphs which are essential to diagnostics and fault handling. Lines should reconnect promptly and ideally only be off for a few seconds, but, as usual, this very much depends on the routers and some lines make take a few minute to reconnect. There may be a second controlled PPP restart for some lines that end up on the wrong LNS once lines have stabilised.

We normally do LNS switch overs without a specific planned notice - the process is routine for maintenance and means clearing the PPP session to reconnect immediately on another LNS. We do one line at a time, slowly. We even have a control on the clueless so you can state preferred time of night.

However, tomorrow morning, we will be moving lines off a.gormless (one third of customers) using a different process. It should be much the same, but all lines will be at one time of night, and this may mean some are slower to reconnect.

This plan is to do this early morning - the exact time depends on when staff are available. Sorry for any inconvenience.

Resolution Completed as planned. Graphs back from now on a.gormless.

As we advised, we have had to make some radical changes to our billing to fix database load issues. These have gone quite well overall, but there have been a few snags. We think we have them all now, but this month we had to revert some usage charging giving some free usage.

We have identified that quarterly billed customers on units tariffs were not charged, so these are being applied shortly as a new invoice. Anyone with excess usage as a result, please do ask accounts for a credit.

We have also identified that call charges have not been billed - these can be billed to date if anyone asks, or if you leave it then they should finally catch up on next month's bill.
