While that lasts, you can't be charging a flat $200 in a world where the other players are charging 5-10¢/GB of egress.
But I guess nobody's really pushing traffic so nobody cares about $/GB.
Their pricing's insane in a world where you can get prices not too far from that wholesale rate for CDN service (which is a whole different beast from having one or two colo'd servers).
And anyway, nobody pushing serious bits is paying public rates, anywhere. Those discounts can be huge. In fact I wouldn't be surprised if part of the reason cloud providers have such high rates is so they can give their counterparts an easy, very impressive-looking "win" in negotiations.
This applies to all "enterprise software" too, btw. We've had quotes from vendors that started at 50% off list price, and then negotiated down further from there. It's pretty ridiculous.
