DDOS solution recommendation

While it indeed is true that attacks up to 600 gbit/s (If OVH and 
CloudFlare's data is to be believed) have been known to happen in the 
wild, it's very unlikely that you need to mitigate anything close.

The average attack is usually around the 10g mark (That too barely) -- 
so even solutions that service up to 20g work alright.

Obviously, concerns are different if you're an enterprise that's a DDoS 
magnet -- but for general service providers selling 'protected 
services,' food for thought.
