Then it is 0.89 per TB and that's for UK customers. French customers and customers who sign up through ovh.com get a completely different bandwidth structure. They get "unbilled" bandwidth but only get a few hundred mbps dedicated with each peer. Google it. It's due to competition from online.net in france.
10gbps makes sense if you also have 1gbps servers in their network.
BTW Sonic.net is $70/m. The article was mistaken.
