We graph our customers usage of their T1s, colocation, DS3s, and
virtual web hosting and we charge for their usage based on a formula
that is on our web site. (we don't charge for the top 95th but we
also don't charge for average utilization either)
We do this because we need to charge people for their usage and number
of bytes transferred a month doesn't count right.
ie: 64Kbps 24x7 for 30 days i 20,736,000,000 bytes in a month.
If a customer of ours sustained 64Kbps 24x7x365 I would not care as
that isn't much bandwidth.
But many sites don't do all that much and then spike (like any
business site!), we need to charge for bandwidth over a certain level
(we chose 64Kbps :) to cover usage for these 'peak' periods since we
need to always have bandwidth for the peak usage of *all* of our

A challenge to yourself to write?
