Connectivity at the office of President of India


 
Out of curiosity, I put an RTI asking President of India’s Secretariat about connectivity at President’s office.
 

Questions I asked and their replies

Question 1: Who is the Internet service provider?
Reply: National Informatics Centre meity is providing internet service at President Office.
Question 2: Speed of Internet connection at President’s Office?
Reply: Presently the speed is 100 Mbps.
Question 3: (And my favourite!) Is IPv6 deployed?
Reply: IPV6 supported by most devices. However, IPV4 addressing is used at present.
Question 4: How much internet connection costs at the President’s Office?
Reply: NIC, being a Government Department provides connection on its own budget. The President Office does not incur any expenses towards this.
 
100Mbps seems interesting and actually decent enough to get the job done. I wish they also had support for IPv6. Probably I should not put an RTI asking NIC on their IPv6 support plans for the President’s Office! 🙂
 
Raw RTI reply is here.

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. It’s quite common that Facebook.com (or Google.com for the logic) would be hosted on some server at a large PoP while FNA (or GGC) would serve only specific static content out of it. FNA, of course, sits on the IPs of the ISP hosting it.
So in the source list, we found scontent.fktm1-1.fna.fbcdn.net and that gives an idea that FNA strings are around logic: scontent.fxxx1-1.fna.fbcdn.net where xxx is the airport code. 1-1 means 1st PoP in 1st ISP over there probably (strong guess!). If there are more FNA nodes in a given area, the number goes further up. The team used it and for now, the project is over. But while I was on the way back to India, I thought that this is very interesting data if we pull the full picture by querying all possible IATA airport codes with a logic.
This logic can be used for two things:

  1. Finding locations of all FNA nodes and plot them on the map
  2. Find which networks/ASNs in the world host it

In my check with a script querying it all, I found there are 1689 of FNA’s nodes deployed across the world. Here’s a map of the presence of FNA:

Some of the interesting regional stats from the data

India

Bharti Airtel AS9498 is hosting Facebook caching FNA nodes at Bangalore, Mumbai, Calcutta, Delhi, Hyderabad, Chandigarh, Jaipur, Chennai and Patna i.e 9 cities while in case of Jio they are hosted in 19 cities – Agra, Ahmedabad, Bhubaneswar, Bhopal, Bangalore, Mumbai, Calcutta, Cochin, Delhi, Delhi, Guwahati, Hyderabad, Jammu, Jaipur, Madras, Nagpur, Patna, Simla, Srinagar. IDEA Cellular has them at 6 locations Bangalore
Mumbai, Delhi, Hyderabad, Indore and Pune.

Limitations of data

  1. As I often say – what is there is there. There can be more which is not there in data.
  2. Mapping is based on airport codes and it’s a common practice to use airport codes in DNS records. Actual node location may be within a 100-200km radius of the airport code.
