Particular website is not opening

I am facing a very weird problem right now. One particular website (mondotimes.com) is not opening in my browser. I have tried all the possible solution described on other post of this forum but still no good. Most weird thing is when i am trying to open the above website with my cellphone it's opening without any problem.

• • My cell phone network and my pc network are same as i am using cellphone internet over wifi-hotspot in my pc.
  • When i am trying to open the website with a broadband connection provided by local ISP then it's opening

Now question is

• • • If there is any problem associate with my cellphone internet connection then why it's opening in cellphone browser?
    • If there is any problem with my pc then why the website is opening while it's connected to broadband network?

Please help me out, it's really frustrating.
