Cloudflare CDN Routing Anomaly Detailed Test Across Multiple DNS Resolvers

Here are some key details about my testing location and ISP:

Testing Location: Kolkata, India
Expected Cloudflare CDN edge: CCU
ISP Name: Reliance Jio Infocomm Ltd.

Important Note: Keep an eye on the value of colo on the following response. As that value will show exactly from which Cloudflare CDN edge the data is getting served from. Moreover these 3 letter colo values are basically the IATA airport code on that city. So, you can use a website like World Airport Codes to find out the exact City and Country Name.
