It all started three months ago, when a CloudFlare technician noticed a massive attack against a small site in Ukraine. The content-delivery company offers some level of DDoS protection for free, but only up to a point — once a targeted site clears more traffic than the free network can handle, CloudFlare has to dump it off. The technician glanced at the Ukrainian site — a jumble of Cyrillic characters — then dumped them before the traffic became overwhelming. Today, CloudFlare is announcing its answer to the problem, a massive anti-DDoS program known as Project Galileo.
