A DDoS, or distributed denial-of-service is a malicious attack where excessive amounts of requests are sent to a target. It’s intended to crash a website or server, affect performance and availability for legitimate traffic, or increase hosting and resource cost.
Google has recently reported that their Cloud Armor service blocked a DDoS attack of 46 million requests per second. As an example, that is the amount of traffic Wikipedia receives in a day all in a 10-second span. Cloud Armor Adaptive Protection was able to analyze and intercept this attack as it ramped up, recommending a security rule for the host to mitigate it.
This DDos attack is much larger than the last record of 26 million requests per second blocked by Cloudflare.
