[e2e] congestion pricing in action...

Seen in another context, and forwarded largely for amusement..

[The provider in question measures usage with 5 minute granularity, and
charges extra if the 95th percentile bandwidth exceeds a threshold..]

Due to the way <deleted> does billing, once we burst over our 1/4
meg bandwidth limit in any five minute period, there is no additional
cost to really leaving that limit in the dust :-)

In an average 30 day month, we can burst over our limit for 432 five
minute slices without any extra charges.  This averages about 14
slices per day.

So, I am declaring six of those slices each day, totalling 30 minutes,
to be the collective bursting window.  If you have any cron-executed
backups, large transfers, or other bandwidth-needy tasks to run,
please set them to run between 4:31am and 4:59am.  The extra minute
missing on either end is so those of you with poorly synced clocks
still land in the window.

This leaves plenty of additional bursting time for when random use
causes us to exceed the 1/4 mbps threshhold.
