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?

[1] A pathetic and futile one, so different from the rest.

[2] Subsitute OVH for any half decent provider that isn't really oversubscribed.
