We do not bill you anything extra when it comes to our FUP. The price on our website is the price you'll pay - no strings attached.
We have recently changed our FUP (this will be changed on our website shortly):
Generally if you follow the guidelines below, no shaping would be applied to your account:
1. Do the majority of your downloads during 12:30 am - 7am
2. If you continue to download a lot even when you are throttled then the following month you will be put in the throttled pool earlier
3. If you have a month where you do not download anything, then you will be allowed to download more in the following month before being throttled, so only download stuff that you need so that when you need to download a lot, you can
So in short, the initial bandwidth on our shaped uncapped service is unshaped. If you use the guidelines above, you would stay in the unthrottled pool. If you are in violation of the FUP, your service would be throttled until the beginning of the following month.
