I was under fire right now.
One cellular company, Idea, whose Internet service works really good, was blocking port 22.
And other, BSNL, which works terrible at my home, and is not working recently, since last few days( Maybe be data pack was over ), atleast support port 22.

Just got the call from client who has to send sms to all its clients, immediately. So BSNL was not working. And Idea was not supporting port 22.
Still, I gave IDEA Cellular, a try, and luckily it worked today. They started supporting port 22, at the right time.
My ASS is Saved
