Cloudflare 1.1.1.1 outage Post Mortem and Monocle
Recently I read quite interesting 1.1.1.1 DNS outage post-mortem from Cloudflare: https://blog.cloudflare.com/cloudflare-1111-incident-on-june-27-2024
It’s really fascinating to read about BGP security and at the same time quite concerning that some Tier-1 ISP still doesn’t have proper BGP security in place.
When I read technical details of the post-mortem - I also found out about Monocle tool that allow to investigate BGP routing (issues): https://github.com/bgpkit/monocle
Btw, Monocle is written in Rust :)
