UPDATE(12/2015): Do read the end of the post for more info
I have no clue as to why BSNL( a popular telecom operator/ISP) took this massive step to block the WhatsApp message service or it even maybe an accidental disruption to the popular social messenger service. But there are a few things you can do to get around this blockade IF you own an android phone
Step 1: Root you Phone. Yes you will lose warranty but if you want communication you must choose. Its specific to your Android phone model so you will have to Google.
Step 2: Install Orbot from the Google Play Store. Its Tor for android, which provides anonymity and privacy for users.
Step 3: Enable these options in Orbot Settings.
Step 4: Activate Tor by doing a long press on the icon on the main screen. Enjoy
Note: Connection might be slow. May also take some time to connect for the first time.
YOU USE IT AT YOUR OWN RISK. INFORMATION IS PROVIDED AS IT IS. DO NOT SUE ME IF YOU HAVE DATA LOSS, DAMAGED PHONE OR LEGAL IMPLICATION/RISKS/LOSS. I DO NOT GUARANTEE YOUR ANONYMITY AND PRIVACY. YOU ARE SOLELY RESPONSIBLE FOR WHAT YOU DO.
ORBOT USAGE GUIDELINES:
DO NOT USE IT TO DOWNLOAD OR UPLOAD LARGE FILES. PEOPLE USE THIS SOFTWARE IN DIFFERENT COUNTRIES TO CIRCUMVENT CENSORSHIP DUE TO BAD POLICIES OR INTERNET USE RESTRICTION. BE KIND. BE PATIENT. IT IS SLOW BUT IT DEFINITELY WORKS.

*UPDATE –> The issue seems resolved though there is no official word from BSNL and WhatsApp. If You still experience problems, blockade or live in a country with censorship or strict internet rules the above method can still be followed.
Lot has changed in the Orbot Tor App. Things should be much more simple.
Another thing you could try is to change DNS settings to Google DNS/Open DNS.
