I don't think it's a traffic issue, the packet loss is 24hours a day, even at weekends. This is also a business connection so I'd be surprised if it was a contention issue. As you say, other traffic seems mostly fine (some sites do seem to take longer to load) but our connection speed has dropped from about 16Mbit to less than 6Mbit.

We haven't had a chance to test the line yet, I suspect it might be noise or something but we'll see.
