Cloudflare successfully blocked a record-breaking 11.5 Tbps DDoS attack, demonstrating its unwavering dedication to protecting the global digital landscape.

  • Cloudflare successfully blocked a record-breaking 11.5 Tbps DDoS attack.
  • The attack originated from Google Cloud and was part of an extended wave of assaults over several weeks.
  • Cloudflare's defenses thwarted the assault, showcasing its technical prowess and commitment to cybersecurity innovation.
  • The record-breaking attack highlights the need for robust defense mechanisms to counter hyper-volumetric attacks.
  • Cloudflare's ability to block hundreds of massive DDoS assaults over several weeks demonstrates its resilience and adaptability.



  • Cloudflare has once again demonstrated its unwavering dedication to protecting the global digital landscape by successfully blocking a record-breaking 11.5 Tbps DDoS attack, a feat that not only showcases the company's technical prowess but also highlights the ever-evolving nature of cyber threats.

    In a recent announcement made on X, Cloudflare revealed that it had thwarted this unprecedented assault, which comprised a UDP flood originating from Google Cloud. This massive attack was part of an extended wave of assaults that spanned several weeks, with Cloudflare ultimately emerging victorious in its quest to safeguard the integrity of digital communications.

    The record-breaking DDoS attack in question peaked at 11.5 Tbps, thereby eclipsing Cloudflare's previous benchmark for hyper-volumetric attacks. This staggering figure represents a significant escalation in the scale and complexity of cyber threats, underscoring the need for robust defense mechanisms to counter such assaults.

    What is notable about this incident is that it occurred amidst weeks-long waves of similar attacks, with hundreds of massive DDoS assaults having been autonomously blocked by Cloudflare's defenses over the past few weeks. This remarkable display of resilience and adaptability demonstrates the company's commitment to staying at the forefront of cybersecurity innovation.

    The attack itself was a UDP flood that primarily originated from Google Cloud, with an average of 21,925 ports per second targeted during its peak. Additionally, the assault included a variety of other vector-based attacks such as QOTD, Echo, NTP, Mirai, Portmap, and RIPv1, further underscoring the multifaceted nature of this cyber threat.

    Notably, Cloudflare observed that 99.996% of the traffic in the attack was classified as UDP floods, highlighting the reliance on this protocol for large-scale DDoS assaults. The fact that only a small fraction (0.004%) of the traffic involved other vector-based attacks underscores the growing importance of developing robust cybersecurity solutions capable of addressing such diverse and multifaceted threats.

    The scale and complexity of modern cyber threats necessitate an unwavering commitment to innovation, collaboration, and vigilance on the part of cybersecurity organizations like Cloudflare. By consistently pushing the boundaries of what is thought possible in terms of DDoS protection, these companies serve as beacons of hope for a safer digital future.

    Moreover, this record-breaking DDoS attack serves as a poignant reminder of the importance of robust cybersecurity measures and the need for continuous vigilance in the face of an ever-evolving cyber threat landscape. By staying at the forefront of cybersecurity innovation and working tirelessly to develop cutting-edge defense solutions, organizations like Cloudflare play a vital role in safeguarding the integrity of our digital world.

    In conclusion, Cloudflare's unwavering dedication to protecting the global digital landscape has once again been demonstrated through its successful blockage of a record-breaking 11.5 Tbps DDoS attack. As the cybersecurity landscape continues to evolve and intensify, it is crucial that organizations like Cloudflare remain at the forefront of innovation, collaborating with one another to foster a safer digital future for all.

    Cloudflare successfully blocked a record-breaking 11.5 Tbps DDoS attack, demonstrating its unwavering dedication to protecting the global digital landscape.
