There isn't enough technical stuff on this list any more.
Here's an illustrative graph of a port facing Citylink at the time of the issues :)
All services should now be restored.
If you're still experiencing problems please contact us on 0800 424 895.
If you require an incident report for your own consumption or to pass onto affected customers please let me know and I'll add you to the list :)
I'll follow up later today with a more detailed post explaining what happened.
Sorry for the inconvenience.
