One of my friend told me on error coming for http://www.musicindiaonline.com/ which was showing error that website is blocked as per DoT orders. I just checked it now and for now domain is not resolving at all! Quick analysis to see how site is blocked.  

anurag@laptop:$ dig musicindiaonline.com a ; «» DiG 9.8.1-P1 «» musicindiaonline.com a ;; global options: +cmd ;; Got answer: ;; -»HEADER«- opcode: QUERY, status: NOERROR, id: 23431 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;musicindiaonline.com.

Clearly no error reply along with no A record return as well. This clearly indicates zone is there on DNS resolver itself and I can confirm it by looking for NS/SOA records on the resolver. I am testing this from my village connection on BSNL.

anurag@laptop:~$ dig musicindiaonline.com ns ; «» DiG 9.8.1-P1 «» musicindiaonline.com ns ;; global options: +cmd ;; Got answer: ;; -»HEADER«- opcode: QUERY, status: NOERROR, id: 17114 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 2 ;; QUESTION SECTION: ;musicindiaonline.com.

If we look at gTLD root for delegation of domain name, we get:

anurag@laptop:$ dig com. ns +short c.gtld-servers.net. d.gtld-servers.net. e.gtld-servers.net. f.gtld-servers.net. g.gtld-servers.net. h.gtld-servers.net. i.gtld-servers.net. j.gtld-servers.net. k.gtld-servers.net. l.gtld-servers.net. m.gtld-servers.net. a.gtld-servers.net. b.gtld-servers.net. anurag@laptop:$ dig @c.gtld-servers.net. musicindiaonline.com. ns ; «» DiG 9.8.1-P1 «» @c.gtld-servers.net. musicindiaonline.com. ns ; (1 server found) ;; global options: +cmd ;; Got answer: ;; -»HEADER«- opcode: QUERY, status: NOERROR, id: 46992 ;; flags: qr rd; QUERY: 1, ANSWER: 0, AUTHORITY: 3, ADDITIONAL: 3 ;; WARNING: recursion requested but not available ;; QUESTION SECTION: ;musicindiaonline.com.

Clearly difference in NS records. Thus primarily seems like a DNS based blockage.  I can actually use Google Public DNS and find IP of site and test connectivity:

anurag@laptop:$ anurag@laptop:$ dig musicindiaonline.com a @8.8.8.8 +short 31.7.63.244 anurag@laptop:$ telnet 31.7.63.244 80 Trying 31.7.63.244… Connected to 31.7.63.244. Escape character is ‘^]’. HTTP GET www.musicindiaonline.com

400 Bad Request

nginx/1.1.0 Connection closed by foreign host. anurag@laptop:$

Works! So you can go ahead and blame the bird named DNS for blocking your music! ;)
