It's not even a week when the very famous giant company, Facebook bought WhatsApp for 19 billion dollars. And soon after this news, WhatsApp's server went down for about 4 hours.

Here is what WhatsApp tweeted during the outrage:

sorry we currently experiencing server issues. we hope to be back and recovered shortly.

It's not vague to say that just when the WhatsApp's server went down, the number of visitors increased to a great extent on WeChat, Line, Viber and most importantly on Facebook. What were you trying to do Mark ? It looks like a wise step taken by Mark just to increase visitors on Facebook.
