Mapping Facebook's FNA (CDN) nodes across the world!
Just back from APRICOT 2018. As I mentioned in my previous blog post, APNIC had its first Hackathon and it was fun (blog post of APNIC here). There was one project on the ranking of CDNs using RIPE Atlas data. To achieve this team was trying to find strings/hostnames which they can trace to and figure out nearby CDN. As part of that, I suggested them to look into www.facebook.com and carefully noting the sources from where elements get loaded.
