Inefficient IGP can make eBGP go wild!

Anurag Bhatia
Lately, I have been struggling to keep latency in check between my servers in India and Europe. Since Nov 2021 multiple submarine cables are down impacting significant capacity between Europe & India. The impact was largely on Airtel earlier but also happened on Tata Comm for a short duration. As of now Airtel is still routing traffic from Europe > India towards downstream networks via the Pacific route via EU > US East > US West > Singapore path.

Why Indian internet traffic routes from outside of India?

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.

Tata - Airtel domestic peering IRR filtering and OpenDNS latency!

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 5 208.67.222.222 PING 208.67.222.222 (208.67.222.222) 56(84) bytes of data. 64 bytes from 208.67.222.222: icmp_seq=1 ttl=51 time=103 ms 64 bytes from 208.67.222.222: icmp_seq=2 ttl=51 time=103 ms 64 bytes from 208.67.222.222: icmp_seq=3 ttl=51 time=103 ms 64 bytes from 208.

Routing with North East India!

A few weeks back I got in touch with Marc from Meghalaya. He offered to host RIPE Atlas probe at Shillong and that’s an excellent location which isn’t there on RIPE Atlas coverage network yet. It took around 5 days for the probe to reach Shillong from Haryana. I think probably this probe is the one at the most beautiful place in India. :) Now that probe is connected, I thought to look into routing which is super exciting for far from places like Shillong.
