See [1]: "We don't offer raw infrastructure without service." That is, support is included in the cost. Lots of people don't need support or don't want to pay for it, particularly the startup-oriented crowd here on HN. But I would be interested in a comparison of Rackspace's support to others'.
Rackspace charges you $120 per terabyte of data transfer
Is this in the fine print somewhere? I wouldn't be surprised, but I don't see it mentioned in [1].
