    TalkTalk say they have fixed this. We'll be checking overnight to be sure :-)

    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.
