Well... There's a universal truth about an attack, someone must eat it. However, if you are smart about it, you can detect the pattern of an attack and drop requests after making the minimum amount of work possible.

My former employer offered DDoS protection by putting sophisticated filters and beefy machines to soak attacks. By putting all those huge resources in common, it was possible to help everyone at once. Attacks were mitigated in seconds, it was quite beautiful to see.

I don't think anyone matches those defenses right now.

And now for the good news : this is where snapzu is hosted! :D
