We've just wrapped up the first quarter of 2024, and, already, our automated defenses have mitigated 4.5 million DDoS attacks -- an amount equivalent to 32% of all the DDoS attacks we mitigated in 2023. Breaking it down to attack types, HTTP DDoS attacks increased by 93% YoY and 51% quarter-over-quarter (QoQ). Network-layer DDoS attacks, also known as L3/4 DDoS attacks, increased by 28% YoY and 5% QoQ. When comparing the combined number of HTTP DDoS attacks and L3/4 DDoS attacks, we can see that, overall, in the first quarter of 2024, the count increased by 50% YoY and 18% QoQ. In total, our systems mitigated 10.5 trillion HTTP DDoS attack requests in Q1. Our systems also mitigated over 59 petabytes of DDoS attack traffic -- just on the network-layer.
