Cloudflare Blocks Record-Smashing 11.5 Tbps DDoS Attack
Cloudflare recently stopped one of the largest cyberattacks ever recorded, which reached a peak of 11.5 terabits per second (Tbps). The attack used a flood of data traffic to overwhelm systems but lasted only about 35 seconds before Cloudflare’s defenses automatically kicked in and shut it down.
The company explained that its systems have been working around the clock to block hundreds of these high-volume attacks. In this case, the massive surge of traffic came from a mix of compromised devices and cloud services, designed to overload the target’s systems in seconds.
This isn’t the first time Cloudflare has handled an attack of this scale. Just a few months earlier, it stopped another giant wave of traffic that hit 7.3 Tbps. The size and frequency of these attacks are growing rapidly, showing how serious the threat has become.
To understand how dangerous this is, think of a DDoS attack like thousands of people trying to cram through the doors of a stadium all at once. The rush is so overwhelming that no one can actually get in, not even those with valid tickets. In the digital world, this means that websites and online services can become completely unreachable for real users while the attack is underway.
For anyone running online services, the lesson is clear: protecting against these kinds of attacks is no longer optional. Without strong defenses in place, businesses risk major downtime, service outages, and financial losses. Preparing ahead of time with reliable protection is the only way to stay ahead of threats that are getting larger and more frequent.
