Microsoft says it mitigated a 2.4 Tbps DDoS attack on Azure, which is "higher than any network volumetric event previously detected on Azure."

Wow, that's a lot of traffic attempting to bring down services.

The attack traffic originated from approximately 70,000 sources and from multiple countries in the Asia-Pacific region, such as Malaysia, Vietnam, Taiwan, Japan, and China, as well as from the United States. The attack vector was a UDP reflection spanning more than 10 minutes with very short-lived bursts, each ramping up in seconds to terabit volumes. In total, we monitored three main peaks, the first at 2.4 Tbps, the second at 0.55 Tbps, and the third at 1.7 Tbps.
