A DDoS attack is a flood of internet traffic from many different machines. It targets a single device, service, or network with the intent of overwhelming a specific target so that it can’t be used.

Two years later, GitHub, a developer platform that allows users to create and share code, was hit with a 1.3-Tbps (terabit per second) DDoS attack, described at the time as the largest ever.

The largest DDoS attack during the period was measured at 5.6 terabits per second, but has already been overtaken by an attack on April 24th that was measured at 5.8 terabits per second.

DDoS attacks differ from Denial of Service (DoS) attacks in that they rely on different IP addresses. In other words, the attack comes from multiple different sources, rather than just one location.
