I'm looking at the "Compare Plans" page; is DDoS Mitigation part of another feature that I missed, or is it implicit in the service (i.e., a side effect of having a good CDN)? I can ask that an easier way: if my site takes a 10 Gbps hit, which plan would mitigate it? Enterprise? Do you bill for the transfer that you eat?

Genuinely curious and haven't really looked around the site much, and you guys hit my radar when you took on Lulzsec. Can't imagine the plethora of nasties directed at their gear.
