Mapping major CDNs across Indian networks

Anurag Bhatia
I was recently discussing with a friend Jio’s Fifa streaming issues. Considering PNI capacity challenges with other telcos, I wonder if they were serving FIFA streams out of their network or if it would be on some CDN like Akamai. As I was testing, I noticed a couple of megs of flow data with my provider’s local IP. Turns out that was a local Google GGC node in Rohtak and as I try to connect to it, it replies on HTTP port 80 and 443.

OTT and paid peering

Anurag Bhatia
Yesterday there was an article in the Indian paper Financial Express with the title “OTTs may have to pay access charge to telcos”. Quoting a few points from the article: Social media intermediaries like WhatsApp, Facebook and Twitter, and over-the-top (OTT) players like Netflix, Prime Video and Disney+Hotstar may have to pay a carriage charge to telecom service providers Data, particularly video, comprises 70% of the overall traffic flow on telecom networks, and this would grow further with the rollout of 5G services Upon reference from the DoT, Trai is currently studying various possible models under which OTTs can be brought within the purview of some form of regulation According to sources, an interconnect regime is a must between OTTs and telcos because as 5G services grow, there would be immense data/ video load on networks, which may lead to them getting clogged or even crashing at times.

IX management via Gitlab CI!

I was having this discussion with someone recently on possible software to manage an IXP. Lately, IXP Manager has become the de-facto choice for managing IX. It’s a good tool. Nick and INEX team has built a fantastic open-source tool. But I still feel it’s a bit overloaded for a small 1-2 DC IX operation. If I have to set up a small to mid-size IX, I would rather do that with arouteserver instead of IXP Manager as I did in case of BharatIX in Mumbai (until it shutdown!

Workshop on Network Automation 101

Anurag Bhatia
Next week SANOG (South Asia Network Operator Group) event will start in Kathmandu, Nepal. I will be instructing on a 4-day workshop on Network Automation with two fellow instructors. The idea of this workshop is to make fellow Ops / Network engineers familiar with concepts of Docker, Ansible, and Gitlab CI/CD pipeline and ultimately to make use of REST APIs to bind these all together. This is the first time I am doing such a workshop and the content here is built from scratch.

Facebook cache FNA updates - July 2022

Anurag Bhatia
As returning readers of this blog would be aware - I found a trick to find Facebook caching servers around the world during the APRICOT 2018 hackathon. Since then I am running my code again every year to see the changes and publish this report. Previous reports March 2018 here Nov 2019 here April 2021 here Facebook knows! Back in 2019, I was in San Francisco, California for NANOG 75. While roaming around in the lobby, someone read the NANOG card hanging around my neck and greeted me.
