If you are an Etisalat data subscriber, chances are that you haven’t been able to access Whatsapp since yesterday. Whatsapp isn’t down generally, but Etisalat users seem to have issues accessing Whatsapp’s service over their network.
A quick search through twitter shows that the issue is widespread:
@etisalat_9ja please why is my whatsapp not working

I have reached out to Etisalat to try and get an official response from them, and I will update this if I do get one, but if I had to hazard a guess, I will say, it has something to do with the way the Network is processing secure requests, because I also can’t sign into the Playstation Network either.
In any case, if you are experiencing the issue, you are not alone.
Update: I got a response from Etisalat, they say they “are aware of the issue and are working to get it back to normal”.
