I’m interested to hear how you 1) block 2 Tbps of attack traffic 2) save $500k per month in bandwidth charges since blocking at the border means you have to pay for the incoming bandwidth
1. Not sure where you got 2tbps? I said 10gbps, but we use Alamai’s manages Prolexic ddos mitigation. At previous companies we would buy a half dozen of these, put them at different exchanges and buy transit from the biggest aggregators. This would cost about $4m to get started 2. I meant $50k per month, edited. This does not count loss of productivity.
Sound like you are probably just overpaying for bandwidth and/or DDoS protection.
