Yeah, I'll admit that other CloudFlare customers are likely subsidizing the amount of bandwidth I'm using.

Funny thing - back when I was using 10 TB/mo, my site was hosted entirely on DreamHost's $9/mo shared hosting. I moved mostly because I was starting to get several hours a month of downtime - presumably, they were gently nudging me off their service.

I've seen plenty of $60-$100 dedicated servers come with unlimited-use 100Mbit connections, which work out to 16ish TB/mo before you start getting to 50% saturation. Of course, those are still subsidized in that that pricing is possible only because most people who buy it don't max out a 100Mbit connection.

Still, though, S3's 9-12¢/GB bandwidth pricing seems a bit high. Bandwidth at DigitalOcean (presumably unsubsidized) is 2¢/GB, which comes out to a much more manageable $500 for 25 TB.

With dynamic content, CloudFlare has Railgun, which takes advantage of the fact that dynamic content is usually mostly static. Still, though, if you have 25 TB of dynamic content, I presume bandwidth stops becoming the limiting factor in your cost of operation.
