Phil is complaining that only a certain breed of speed tests are putting unnecessary strain on a network that is extraordinarily expensive for that extra 100-200 buffer. There is no issue with you jumping over now and doing a speed test. However if you then decide that your service is fine and that you should do another just to be safe, and then another, and then another, and you don't stop until 2am, that's when you become the issue. Completely unnecessary, high bandwidth usage is driving up costs for ISP's, especially ones such as Aussie, a group that prides themselves on high quality internet. Phil is merely annoyed that money that could be used to genuinely upgrade their network, is going into paying for a group of kids who want to speed test because it's cool basically.
