Verizon CFO - Unlimited is just a word it doesn't really mean anything
There's a few interesting points in this thread that relate to hosting:
consumers "think they consume a lot more data than they really do."
The same has to be said with hosting, I would bet that a large amount of people that sign up to unlimited plans end up using hardly anything. I have unlimited ADSL2 at home, I probably wouldn't use more than 50GB/month.
How much monthly data do you actually use on your hosting plans? We have 3.2TB BW & only used 40GB in the last month (across 5 sites).
