CDN Caching Panel discussion at APNIC 46

Anurag Bhatia
I am in Noumea in New Caledonia in the Pacific Islands. Next week we have APNIC 46 conference and I would be moderating an exciting panel discussion with friends from Akamai, Cloudflare, Facebook and more about working of CDNs. If attending APNIC 46, please come & join this session. If you are interested in connecting to Hurricane Electric (AS6939) in this region, please do drop me a message. (List of our PoPs in the region here)

Encrypted DNS using DNSCrypt

Anurag Bhatia
Writing this post from my hotel room in Kathmandu. I found that many of the servers appear to be DNS resolvers which is unusual. Have a look at these weird DNS replies: dig @anuragbhatia.com . ns +short a.root-servers.net. b.root-servers.net. c.root-servers.net. d.root-servers.net. e.root-servers.net. f.root-servers.net. g.root-servers.net. h.root-servers.net. i.root-servers.net. j.root-servers.net. k.root-servers.net. l.root-servers.net. m.root-servers.net. dig @google.com . ns +short b.root-servers.net. c.root-servers.net. d.root-servers.net. e.root-servers.net. f.root-servers.net. g.root-servers.net. h.root-servers.net. i.root-servers.net. j.root-servers.net. k.root-servers.net. l.root-servers.net. m.root-servers.net. a.root-servers.net. This seems unusual and is the result of basically port 53 DNS hijack.

Notes from SANOG 26 - Mumbai

Anurag Bhatia
Just finished with SANOG 26 conference and tutorials. It went very nice. Interestingly this time conference did not start early morning like it did in SANOG 24 at Noida. It was rather late in afternoon. Also, on very good note - there were less Govt. bureaucrats to bore attendees with usual stuff they always talk about but have very little idea. One specific interesting presentation was Opportunities and Challenges for Broadband Wireless in India by Prof Abhay Karandikar (from IIT Mumbai).

Different CDN technologies: DNS Vs Anycast Routing

Anurag Bhatia
And I am back from Malaysia after attending APRICOT 2014. It was a slightly slow event this time as less people came up due to change of location from Thailand to Malaysia. But I kind of enjoy the APRICOT in start of year. :) It has been quite sometime when I blogged. After getting into Spectranet I got relatively more busy along with bit of travelling to Delhi NCR which has been taking lot of time.

Google Public DNS and Akamai issues in India

Anurag Bhatia
A quick blog post on a interesting issue coming up due to combined problem of CDN failure on Google Public DNS and bad Akamai performance due to Tata-NTT peering issue. I was trying Zembra mail since there’s no more free Google Apps edition and one of my friend asked me to basic email on his domain up. It was more or less a straight task by installing Zembra with decent GUI.
