CANI SMC - Submarine cable connecting Andaman and Nicobar islands

Anurag Bhatia
Earlier in March I visited Andaman & Nicobar Islands. The trip was purely personal as my wife happened to have been born there. These are Indian islands in the Bay of Bengal located in the South East of West Bengal and geographically quite near Myanmar and Thailand. The nearest large Indian cities on the mainland are Kolkata and Chennai. In the initial part of the trip, we stayed in Swaraj Dweep (old name Havelock islands) and later in Port Blair.

Jio-Airtel PNI up in Delhi NCR!

Anurag Bhatia
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.

Self hosted open source mesh VPN with IPv6 support!

Anurag Bhatia
A rather long title but the post is about self-hosted open-source mesh VPN with IPv6 support and works with nodes behind CGNAT! This will be a long post documenting the concept of mesh VPN, the problem it is solving as well as a working demo. If you are not planning to deploy it right away, you can skip the post after the “Configs and setup” section. Problem I am running a site-to-site VPN for a long time between various servers located far away from each other.

Last month I got access to Jio 5G like everyone else around in Haryana. They are running a beta program with uncapped data for now. Overall it works fine for usual stuff (web surfing on popular sites, YouTube videos, music streaming etc) but 464XLAT seems to be a little buggy in IPv4 hardcoded destinations. Initially it was giving quite a few issues but many of them seem to be fixed in last few days.

Why object storage is getting exciting?

Anurag Bhatia
Last year had many interesting developments and one of that has been object storage. For those unaware, object storage is de-facto cloud storage which stores data as objects instead of file system architecture. This gives the option of simple plug-and-play horizontal scalability. It became popular when Amazon Web Services (AWS) launched S3. The idea was straightforward - pay-as-go storage with a few cents/GB/month charge to store data and a few cents/GB to egress data.
