INFORMATION
  • INITIAL
    6¼ years ago by Andrew

    We are seeing a denial of service attack, which is causing more problems that usual, and this is disrupting traffic to some customers - but it is moving, and so different customers at different times.

    Obviously we are working on this, and unfortunately cannot say a lot more of the details.

  • UPDATE

    We are still seeing problems, customer on this LNS would have seen drops and routing problems. We are working on this.

  • UPDATE
    6¼ years ago by Andrew

    This problem has also been affecting some of our transit routes, and so routing to parts of the internet will have had problems too.

  • UPDATE

    We are working through this still, we have moved lines off A.Gormless, and have had further problems with those lines. Please do bear with us, we hope things to calm down shortly.

    We cannot go in to a lot of detail but I will say this is a complete new sort of attack. We have made some changes and will be reviewing ways we can mitigate attacks like this in the future. I'll re-open this issue if problems continue. Thank you all for your patience.

    Hmm, that attacker is clearly back from lunch.

  • UPDATE

    Not gone away - we are working on more...

  • UPDATE

    This now appears to be affecting VoIP too.

  • UPDATE
    6¼ years ago by Stuart

    We're rebalancing some lines due to the issues early morning today as per https://aastatus.net/2457 and additionally due to today's issues.
    Some PPP sessions will disconnect and shortly reconnect. This is to fix an imbalance in the number of sessions we have per LNS.

  • UPDATE
    6¼ years ago by Adrian

    The line rebalancing is fine, and mostly broadband is fine, but we are tackling a moving target aiming at various services on an ongoing basis.

  • RESOLUTION
    6¼ years ago by Andrew

    Quiet for now, we are monitoring still.
