As returning readers of this blog would be aware - I found a trick to find Facebook caching servers around the world during the APRICOT 2018 hackathon. Since then I am running my code again every year to see the changes and publish this report. Previous reports March 2018 here Nov 2019 here April 2021 here Facebook knows! Back in 2019, I was in San Francisco, California for NANOG 75. While roaming around in the lobby, someone read the NANOG card hanging around my neck and greeted me.
After my last post about home networking, I am jumping back into global routing. More specifically how Indian traffic is hitting the globe when it does not need to. This is an old discussion across senior management folks in telcos, policymakers, and more. It’s about “Does Indian internet traffic routes from outside of India?” and if the answer is yes then “Why?” and “How much?” It became a hot topic, especially after the Snowden leaks.
A friend of mine buzzed me yesterday about his missing route objects. Later multiple other ISPs told the same story which triggered me to put this as a question on INNOG Mailing list. Many folks replied of missing route objects there and it seems to be limited to IRINN members only. I also asked the same question on APNIC mailing list and it was again confirmed about the issue. Before I proceed further, here’s what it is all about.
I had calls with a couple of friends over this week and somehow discussion IPv6 deployment came up. “How much has been IPv6 deployment in India now in 2020” is a very interesting question. It’s often added with - “how much of my traffic will flow over IPv6 once it is enabled”? Game of numbers There is a drastic difference in IPv6 deployment depending on which statistic we are looking at here in India.
Suddenly the voice market in India is becoming very interesting. Earlier it was the case of Jio (and competitors) launching unlimited voice plans and now it’s the case of Govt. of India permitting IP telephony. IP Telephony i.e networks where telephony happens over IP (not to be confused with IP to IP calls but) where IP to PSTN interconnects happen. Till a few months ago IP telephony (or IP-PSTN) interconnection was allowed only under certain conditions like doing it inside a building only for purpose of call centres (with OSP license) or running SIP trunks over private networks.
