Yikes! But there is a short "rest period" at about 15:30. If that is when streaming stopped for a few minutes then things might not be too bad in general. If it was independent of your usage I would be concerned that someone is leeching off your connection.
I recommend stopping all activity for a defined 30 minutes startng at an hour point, and see if we get a nice clean patch. Or at any point if hitting on an hour point within a couple of minutes is difficult.
Fix a new BQM of course
