I came home for the vacation and realized that I am not able to access certain websites from my laptop. I can't access coursera.org, amazon.in and more sites.
I was able to access them when I was in college from the same laptop but the ISP was different. I had no problem accessing the websites when I came home a few months ago.
I use this laptop to share internet to other devices (my mobile) by following this answer. And strangely enough, my mobile which used the laptop in question as gateway is able to access the websites without any trouble!
Here is the output of traceroute and below given is the output of ifconfig:

I am running Ubuntu 14.04 and my ISP is BSNL.
