INFORMATION
  • INITIAL
    10 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
    10 years ago by Andrew

    We're still working on this....

  • UPDATE
    10 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
    10 years ago by Andrew

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

  • UPDATE
    10 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
    10 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
    10 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
    10 years ago by Adrian

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

  • UPDATE
    10 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
    10 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
    10 years ago by Adrian

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

  • RESOLUTION
    10 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
