Very interesting. It makes me wonder whether this is a contributing factor to some users who experience stuttering on an otherwise powerful system, while another user with the same or similar system is as smooth as silk.
In the UK, most ISPs use the OpenReach network which is owned by BT or British Telecom, (I think Sky has it’s own equipment or did they ditch it?). BT is a private company operating it’s own (arguably more expensive) services and products. Therefore, is an ISP that says, “We don’t throttle!” truly in control of that?
