INFORMATION
  • INITIAL
    8¾ years ago by Andrew

    We are investigating a network issue affecting most customers with packet loss - this impacts broadband, ethernet, VoIP, and all services.

  • UPDATE
    8¾ years ago by Andrew

    We're still working on this....

  • UPDATE
    8¾ years ago by Andrew

    We are being severely DOS'd, our usual anti-DOS systems have not helped this time due to the nature of the attack. Needless to say, we are working to mitigate this.

  • UPDATE
    8¾ years ago by Andrew

    Things are not perfect, but we have mitigated most of the problems

  • UPDATE
    8¾ years ago by Andrew

    The network has been stable for over an hour now. There are are a very small number of customers who are offline. We will be contacting them in the morning, However do call our Support Team from 8am.

  • UPDATE
    8¾ years ago by Adrian

    Whilst service is mostly stable, we are going to have to do more work on this during the day. We'll try and keep disruption to a minimum.

  • UPDATE
    8¾ years ago by Adrian

    The DDOS has moved to a new target block which has caused more problems again - we are working on this still, but service is improving again.

  • UPDATE
    8¾ years ago by Adrian

    Looking good now - a handful of customers off line totally but we are working on that now.

  • UPDATE
    8¾ years ago by Andrew

    Side Note: This wasn't an attacks against our network or servers specifically, it wasn't a 'hacking' attempt like we've seen in the news recently. This was a denial of service attack, probably, against a particular customer. We may not get to the bottom of why this customer was attacked but we are investigating.

  • UPDATE
    8¾ years ago by Adrian

    Some customer are having their WAN IP address changed to get them on-line. Some customers with blocks of IPs are being contacted regarding a change of IP address block. Obviously if you need the IP to be reinstated once this issue is resolved, we are happy to do that.

  • UPDATE
    8¾ years ago by Adrian

    Looking a lot better now - monitoring carefully. Impacted customers should now be on line.

  • RESOLUTION
    8¾ years ago by Andrew

    Whilst the attack has now stopped, we have a number of things we still need to do. Thank you for your patience and understanding. More details http://aa.net.uk/news-20151119-dos.html
