We unpack a recent incident at Quad9, ​​a public DNS resolver, and how enterprises can approach security in light of how BGP is designed.

This is the Internet Report, where we uncover what’s working and what’s breaking on the Internet—and why. On this episode, ThousandEyes’ Principal Solution Analyst, Mike Hicks, is joined by Kemal Sanjta, Principal Internet Analyst at ThousandEyes. They unpack the recent incident at Quad9, ​​a public DNS recursive resolver, through the lens of ThousandEyes Internet and Cloud Intelligence. They walk through their learnings, including why security is not necessarily a guiding principle behind BGP, how RPKI can help to protect enterprises from similar incidents, and why visibility is the key to identifying and mitigating similar BGP mishaps.
