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 - 169.149.212.122. 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!
I just presented data on Performance of Root DNS anycast in UK & Ireland at INEX meeting.
An interesting promo video on Internet peering and why it is important in context of Africa by Internet Society.
And college started after pretty good holi holidays. Again having bit painful time due to hot weather and this is just start of summers. Well all I can hope is that there won’t be voltage issues in village again (like last time). And just to make sure on that part - I have put 2 RTI’s asking Power department about their preparation details. :)
Anyways coming on blog post topic for the day - the effect of “next-hop-self” at an IXP when there are peers as well as transit customers of a network.
Fest time at college - Good since I get lot of free time to spend around looking at routing tables. It’s always interesting since last week was full of some major submarine cable cuts and has huge impact on Indian networks.
Anyways, an interesting issue to post today about Global IPv6 routing . There are “dark spots” in global IPv6 routing because of peering dispute between multiple tier 1 ISPs involving Hurricane Electric (AS6939) & Cogent Communications (AS174).
