Welcome to India Vultr!

Anurag Bhatia
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.

Redundancy on the servers without BGP

Anurag Bhatia
A developer friend recently asked me about the design of redundancy on servers. He had a valid point - running BGP can be tricky and expensive since most colo & datacenter host would offer simple static routing & usually with just a couple of IP addresses. Furthermore, due to IPv4 exhaustion, the prices of /24 have shot off pretty massively. On top of this burning, a /24 on single or multiple servers is also a questionable design practice unless one of hosting & selling hundreds of virtual machines on those servers.

Designing high capacity home network

Anurag Bhatia
For the last few months, we have been working on setting up a dedicated room for my home office usage. This gives me the opportunity to plan for changes in the home network. Key design ideas Cabling should support needs for now as well as the future but active hardware stays strictly for what I need for now. Hardware can be upgraded easily. It is not impossible to change cabling in the future since we have ducts - 0.

How Does the Internet Work? - Vox

Anurag Bhatia
A nice short 20mins video by VOX on how the internet works. It covers the basic idea of connectivity a higher level and I am probably going to pass this link to friends & family members outside of the networking domain when they ask. It also covers 60 Hudson Street which I visited exactly an year ago. :)

NIXI root DNS servers and updates

Has been a while since I checked the status of root servers which are hosted at NIXI. The list as per their official member list stays the same i.e i root in Mumbai, K root in Noida and F root in Chennai. i root seems to be up! show ip bgp neighbors 218.100.48.75 received-routes There are 5 received routes from neighbor 218.100.48.75 Searching for matching routes, use ^C to quit...
