Thanks, that makes perfect sense. Mentioned to the engineer at the cab that I was on a Sky connection but he didn't seem to realise it would make a difference.
Maybe he was new, or in a hurry for his lunch :-(
It matters not which LLU ISP you are with, as OR we only have access to classic BT owned circuits via our CSS database.
You'll have noticed how many wires are in those Cabinets, we need to know the dedicated routing from your ISP in order to identify 'your' connections manually, or to employ a 'Remote tone' which generates an audible noise that we can then identify.
However, as you have since found out, the issue was nothing to do with the engineer you spoke with and we can't be spending time looking at every EU's problems as they pass us when we're working, we simply haven't got the time. The simplest way is to ring your ISP immediately you encounter an issue
