BGP is vulnerable to routing hijacks and path leaks that negatively impact traffic on the Internet. RPKI helps solve some of these problems, but for some forged paths, we need to rely on a simpler mechanism: First AS enforcement in BGP.
ASPA is the cryptographic upgrade for BGP that helps prevent route leaks by verifying the path network traffic takes. New features in Cloudflare Radar make tracking its adoption easy.
Cloudflare Radar has added new tools for monitoring PQ adoption, KT logs for messaging, and ASPA routing records to track the Internet's migration toward more secure encryption and routing standards.
There has been speculation about the cause of a BGP anomaly observed in Venezuela on January 2. We take a look at BGP route leaks, and dive into what the data suggests caused the anomaly in question.
A BGP “zombie” is essentially a route that has become stuck in the Default-Free Zone (DFZ) of the Internet, potentially due to a missed or lost prefix withdrawal. We’ll walk through some situations where BGP zombies are more likely to rise from the dead and wreak havoc.
Cloudflare Radar has evolved significantly since its 2020 launch, offering deeper insights into Internet security, routing, and traffic with new tools and data that help anyone understand what's happening online.

The Internet is a vast, sprawling collection of networks that connect to each other. The new Cloudflare Radar Routing page monitors routing changes and anomalies and presents statistics about how we see traffic getting routed on the Internet
Routing on the Internet follows a few basic principles. Unfortunately not everything on the Internet is created equal, and prepending can do more harm than good. In this blog post we’ll talk about the problems that prepending aims to solve, and some alternative solutions
