Finally I managed to move my blog to custom domain www.naanushande.com
The urge to move the blog custom domain started when the blogspot domain was blocked in our office blocked. So, 45 days back I registered naanshande.com domain with Webcom Systems. A slight miscommunication between myself and vendor delayed the transition. I took help of Aditya PK to trouble shoot the issues. Yesterday I was able to do right configuration of CNAME record using this link. I didn't expected that a single dot would be so crucial. Anyway, All's Well That Ends Well.
Couple of points to be noted:
In case of any issues, please let me know immediately.
