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.
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.
Since last week of Nov 2019, I am having serious issues with Airtel at my home. Somehow 4G signal SNR is very poor and most of the calls just fail on that. Airtel support just mentioned that they are putting a new site in my area in Jan 2020 but fail to explain why suddenly it went so bad. I can imagine that support team staff does not have visibility to network in real-time and likely it would be an issue with the 4G antenna on one or more towers.
Last month I noticed quite high latency with Cisco’s OpenDNS from my home fibre connection. The provider at home is IAXN (AS134316) which is peering with content folks in Delhi besides transit from Airtel. ping -c 5 220.127.116.11 PING 18.104.22.168 (22.214.171.124) 56(84) bytes of data. 64 bytes from 126.96.36.199: icmp_seq=1 ttl=51 time=103 ms 64 bytes from 188.8.131.52: icmp_seq=2 ttl=51 time=103 ms 64 bytes from 184.108.40.206: icmp_seq=3 ttl=51 time=103 ms 64 bytes from 208.
And here goes first blog post of 2018. Last few months went busy with some major changes in personal life. :) I looked into Amazon’s India connectivity with various ASNs tonight. Here’s how it looks like. (Note: Jump to bottom most to skip traces and look at the summary data). Traceroutes Amazon India to Vodafone India traceroute to 220.127.116.11 (18.104.22.168), 30 hops max, 60 byte packets 1 ec2-52-66-0-128.ap-south-1.compute.amazonaws.com (22.214.171.124) 21.861 ms ec2-52-66-0-134.
