Well we have caps here in the Yukon from are only ISP provider and they give us a way to track our usage per month. Let me tell you we do not get anything close to 250 gigs/month cap! Max connection speed is 10Megs, and the monthly cap is 20Gigs/month with 10 dollar charge for every 1 gig you go over. We get to pay 79.95 a month for this privilege.
So be happy with 250Gigs for a monthly cap I say.
