What makes it dangerous is that those requests aren't coming from a single source - it's a distributed denial of service attack. Anybody can push huge throughput from an XL cloud server with good networking, but it's just as easy to block that IP. Blackholing thousands of nodes is much more difficult.

Legitimate IPs, at that. These are networks that are not hostile 99% of the time.
