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.
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 5 184.108.40.206 PING 220.127.116.11 (18.104.22.168) 56(84) bytes of data. 64 bytes from 22.214.171.124: icmp_seq=1 ttl=51 time=103 ms 64 bytes from 126.96.36.199: icmp_seq=2 ttl=51 time=103 ms 64 bytes from 188.8.131.52: 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 184.108.40.206 (220.127.116.11), 30 hops max, 60 byte packets 1 ec2-52-66-0-128.ap-south-1.compute.amazonaws.com (18.104.22.168) 21.861 ms ec2-52-66-0-134.
On weekend I was looking at BGP Instability Report data. As usual (and unfortunately) BSNL tops that list. BSNL is the most unstable autonomous network in the world. In past, I have written previously about how AS9829 is the rotten IP backbone. This isn’t a surprise since they keep on coming on top but I think it’s well worth a check on what exactly is causing that. So I looked into BGP tables updates published on Oregon route-views from 21st May to 27th May and pulled data specifically for AS9829.
So it seems like apart from voice interconnect issues, Jio is also facing routing issues on the backbone. I ran a trace to one of IP’s on Jio network allocated to end customer - 22.214.171.124. I ran trace from all Indian RIPE Atlas probes measurement here. There seem quite a few RIPE Atlas probes which are giving latency on 150ms + range. Seems like they are downstream or downstream of downstream of Tata Comm’s AS4755 and routing is happening via Singapore!
