Looks like it's cleared up now. The earlier stuff on the chart looks horrible. I had a bet with myself that your ISP would be VM and on checking your profile it seems I was right.

I have no idea what went wrong but when there are incredibly bad charts with high packet loss you can bet your bottom dollar it's cable.
