We started using CloudFlare at the end of May 2011 and I was just looking at the numbers and saw our usage of bandwidth went from 2-3k GB per month to 18k+ GB of use per month. Also our Unique vistors dropped from 60-80k to 800ish.
Could CloudFlare be causing these numbers to change so drastically? We host podcasts ourselves and I am wondering if CloudFlare is trying to cache them multiple times causing all this bandwidth usage or something.
