I am not sure the TB/month figure quoted by others is a price that would scale to this level. As a new start-up without the ability/desire to commit for a year or any credit rating, you are likely to be paying about $6 per Mbps per month. As a reference for this price in July 2008, Cogent took the bottom out of the transit bandwidth market by offering $7 per Mbps (dropping to $6 for 1Gbps committ) - (see http://connectedplanetonline.com/mag/telecom_cogent_throws_d...). Prices may have dropped a bit in the last 15 months, but not by that much.

So at 7000 Mbps/second - I'd put the price at more like $42k per month.
