ChillingSilence:freitasm:myfullflavour: ... unlike the energy sector where the measurement is in units, bandwidth is sold as a speed.
Here's the thing: ISPs buy gigabits per second (speed) but sell gigbytes (quantities)...
NBR worked out it costs (ballpark) 6c per-GB internationally?
Yet it's being sold either per-GB for 79c (HD for example) or overage charges at $5 for 2GB (Maxnet).
There's other ISPs though that will happily give you a larger data cap, so the question is: Do customers *actually* care enough to switch ISP's to one that gives them more data at a cheaper price and a better service, simply because they have lower overheads to cover?
Apparently the answer is no...
You can't ignore time of day though - GBs used at 7pm will be an order of magnitude more expensive than GBs used at 3am, in terms of pressure on infrastructure (size of pipe ordered from SXC).
Given that ISPs don't rollover your data month to month (well most of them), its in their interest for you to have too-big a plan for your needs (lots of unused data) and so having prohbitively expensive overage is a great tactic to encourage people to subscribe to big plans.
