INFORMATION
  • INITIAL
    3½ years ago by Andrew

    Due to the recent outages we are needing to investigate in more detail some of our network infrastructure. We are planning to do this from 2AM on Thursday 17th September, and plan to complete the work by 5AM. So as to fully understand and fix the cause of some of our recent problems we may cause some disruption to services. There may be line drops and short periods where there may be limited connectivity. We will attempt to keep this to a minimum, and will update this post throughout the period.

    This work has been completed. There are a couple of outstanding things we still need to work on, but on the whole this has been successful. The main thing being the reboot of a core switch which has fixed most of the problems we've had recently.
