Stopping one vector that makes up the largest of DDoSes certainly isn't a bad thing.

At the risk of starting a "NANOG war" [1], BCP isn't a magic wand. If I find a zero day in the nasty customised kernels that OVH run on their clients boxes, I only need 300 compromised hosts to send 300Gbps of traffic without spoofing the IP or using amplification attacks [2]. I can rent a server with a 10Gbps connection for 1 hour for a few quid/dollars. I could generate hundreds of Gbps of traffic for about £1000 from legitimate IPs, paid for with stolen card details. How will BCP save you then? Can everyone stop praising it like it was a some magic bullet? James. [1] A pathetic and futile one, so different from the rest. [2] Subsitute OVH for any half decent provider that isn't really oversubscribed.
