Yesterday, we celebrated the fifth anniversary of Project Galileo. More than 550 websites are part of this program, and they have something in common: each and every one of them has been subject to attacks in the last month.
Today, we're announcing Spectrum for UDP. Spectrum for UDP works the same as Spectrum for TCP: Spectrum sits between your clients and your origin. Incoming connections are proxied through, whilst applying our DDoS protection and IP Firewall rules.
Efficient packet dropping is a key part of Cloudflare’s distributed denial of service (DDoS) attack mitigations. In this post, we introduce a new tool in our packet dropping arsenal: L4Drop.
It's been a while since we last wrote about Layer 3/4 DDoS attacks on this blog. This is a good news - we've been quietly handling the daily onslaught of DDoS attacks. Since our last write-up, a handful of interesting L3/4 attacks have happened. Let's review them.
Internally our DDoS mitigation team is sometimes called "the packet droppers". When other teams build exciting products to do smart things with the traffic that passed through our network, we take joy in discovering novel ways of discarding it.
