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.
In a recent Network AF podcast Avi Freedman (Kentik) joked with the guest about how he finds who is transit free / tier 1 network. He said, “I ask everyone who they think is a tier 1 network.

I am in Bangalore for two days. While there are many things packed into these two days short schedule, one of the most exciting ones is Google Global Network India Innovation Summit. While Google has presented across various events in past talking about their AS15169 backbone, this is the first summit where they are covering it in detail and that too with the Indian context!
Must say that I find AS15169 quite fascinating on the BGP side of things.
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.

Vultr has announced start of their Mumbai location on 12th of this month. It’s amazing to see them entering India. Always a good thing for growth of cloud computing on demand in India.
Besides Vultr, we have got Amazon AWS, Microsoft Azure, Google Cloud, Digital Ocean, Linode, Oracle Cloud etc in India. I heard OVH also planning for Indian location and so have to see how that goes.
In meanwhile, let’s have a quick check on Vultr’s network connectivity.
