Wow, ~700 TB/mo? That does sound like a lot.
What kind of site would serve that volume of traffic and not have 56k for operating expenses? I mean, I can think of a few examples like Wikipedia maybe, since they are non-commercial and such, but for a commercial business? Maybe 4chan moves that much without a lot of revenue I would think, or maybe... imgur? but not really sure, I mean, it would seem like they could get that amount easily via ads alone.
What was the use case here?
Also, I think that 56k for traffic alone kind of depends on context. I mean, how much does Netflix pay for serving their volume of traffic?
What I'm saying is, isn't 700 TB a month something that would probably be very expensive no matter the context? Just storing 700TB would cost a lot, no?
I'm really curious about your use case here.
