Mapping major CDNs across Indian networks

Anurag Bhatia

I was recently discussing with a friend Jio’s Fifa streaming issues. Considering PNI capacity challenges with other telcos, I wonder if they were serving FIFA streams out of their network or if it would be on some CDN like Akamai. As I was testing, I noticed a couple of megs of flow data with my provider’s local IP. Turns out that was a local Google GGC node in Rohtak and as I try to connect to it, it replies on HTTP port 80 and 443. The port 443 response is rather more interesting because while connecting to IP throws an error, it does give me the SSL certificate out of handshake and now I know it’s indeed Google! :)
