Well, thank goodness the internet is OK!!
Do you know if your ISP counts uploads into your data use? Mine does, it never used to, we had on peak, off peak, and uploads were a completely
separate count. Now I have this fancy "Anytime Quota" which basically means "We've actually removed the good stuff like not counting uploads into
your quota, now your uploads do count as a total, and we've also removed allocated times when you have two separate quotas, on peak, and off peak,
and we've done it in a sneaky that will make you WANT to go back to a prehistoric useage method, by calling it Anytime Quota, and you will lap it
up.. Oh and also, you don't have a choice!"
Also, most ISP data use counters aren't exactly up to date. They update periodically but won't always reflect an exact current usage compared to
what you think..
try using a bandwidth monitoring utility that tracks all your internet usage and can give yo a tally at the end of the day/week/month/year etc.. good
for keeping track of what you actually use. As long as you're the only PC on your home network.
