Six months ago we experienced a 30Gb/sec and 60M PPS attack that was targeting over 1000 IPs on our network. Although we eventually stopped the attack with the aid of our upstream providers, a number of our customers asked us why we didn’t have a DDoS protection service in place.
We decided on NTT’s service due to their scale and network capacity. However, this solution was meant only to protect our network in times of need, and not to protect individual customers on a 24/7 basis. One customer revealed that above all else, DDoS attacks are what keep him up at night.
