Upstream and Downstream log to follow.

The engineer has just visited and after checking all of my equipment found that there was an issue with the box that enters the property where the brading was touching the stinger. He fixed this and re-adjusted the power levels at the cabinet and removed the -15db attenuator that was fitted to the modem.
