Azure DDoS Attack Trends on the Rise in 2021

The Microsoft Azure DDoS Protection team mitigated about unique 360,000 attacks in the second half of 2021. That is a 43% increase from the first half of 2021.

In November, Microsoft mitigated a DDoS attack with a throughput of 3.47 Tbps and a packet rate of 340 million packets per second (pps), targeting an Azure customer in Asia. We believe this to be the largest attack ever reported in history.
