Internet infrastructure is learning from the spammers and other cyber attacks--
Spam war caused failure at critical internet exchange center | The Verge: "The good news is that the web is built on redundancy, so the extra terabit-per-second of bandwidth could be spread across the network without any catastrophic failures, but the wake-up call for telecoms is real. There's never been a DDoS attack against an internet exchange before, and exchanges aren't set up to protect against them. LINX is run as a non-profit collective of ISPs, a kind of no-man's-land between providers, so it doesn't have the resources of multi-national telecom to back it up. And before today, their internal IPs were open to traffic from outside the network, leaving them vulnerable to DDoS attack."
