It's free, man

My ISP has this concept they call "uncounted period". It is a period of time during the day where downloads do not count against your monthly allowance. This is part of the email I have received from them regarding this:

...the allowance for the period 12 midnight to 12 noon each day will be increased to 40 gb from the current allowance of 40 gb.

Generous, aren't they?
