Cloudflare: Sends DDoS Alerts to attacking websites

Cloudflare now allows its customers to generate alerts that alert them when their sites accept attack DDoS.

In a DDoS attack, an attacker "floods" a server or one connection on the internet with more requests than it can handle. This request bombardment renders the service unavailable and the company (or individual) experiences downtime.
