I visited Delhi earlier today and noticed latency from my phone on Jio 5G to my home (on an ISP behind Airtel) was just 20ms. It varied a bit (as one would expect on a wireless radio network) but 20ms is special because until now it was at least 80-90ms. After all, Jio and Airtel were not connected in Delhi NCR until now. There were sometimes jokes about them being connected at NIXI Noida but that never pushed any traffic because NIXI injects its route server AS24029 in the AS_PATH and while their direct PNIs (i.
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.
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 - 184.108.40.206. 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!
Just noticed that Reliance Jio (AS55836) seems to be originating a /16 which is for Charter Communications (AS20115) - 220.127.116.11/16. route-views>sh ip bgp 18.104.22.168/16 long | exclude 20115 BGP table version is 18764390, local router ID is 22.214.171.124 Status codes: s suppressed, d damped, h history, * valid, > best, i - internal, r RIB-failure, S Stale, m multipath, b backup-path, f RT-Filter, x best-external, a additional-path, c RIB-compressed, Origin codes: i - IGP, e - EGP, ?
