Update timeline

  1. investigating Mar 16, 2017, 01:46 PM UTC

    We are investigating an issue preventing DNS Resolving for pbx-01.it-communicationsltd.co.uk we are trying to understand the reason for this. Further update to follow.

  2. identified Mar 16, 2017, 01:51 PM UTC

    We have identified cause of the issue and are now working on resolving it.

  3. monitoring Mar 16, 2017, 02:26 PM UTC

    We have resolved the issue for the moment. IPtables on PBX-02 keep locking up and preventing DNS from resolving, which then caused Asterisk to become unstable. We are reviewing IPtables and the geoip module to better understand what is causing the issue so this issue can be fixed so not to happen in the future. We would like to apologise for any inconvenience caused.
