"mobango.com" or "in.mobango.com" are not opening on my PC-

hi..
since last couple of months..i have been seeing that in many computers (including mine) this website is not opening..all other websites are opening but this particular website is not opening..".. cant find the server at mobango.com"..i had tried to open this website-"mobango.com" or "in.mobango.com" on every browser like (IE6,IE7,Mozilla firefox 3,Opera 9.65,netscape navigator,google chrome) but it didnt open..
i had also checked my firewall settings and security settings of all browsers and also the parental control..every thing is fine and there is no block on this website..but still it encounters problem..
NOTE : i have tried to open this website on my pc as well as on some of my friend's PC's and they also experience the same problem on their Pc's...but one thing to note is that..in my college internet lab..there is one PC on which this website opens perfectly..as per as my knowledge..only on that PC the above mentioned website opens..Why is it so..?? The website opens in that PC and why it is not opening in our PC..I tried to figure out the settings on that PC..and everything is normal..the only thing is that it runs IE4..as its browser.

Plz tell me what i should do ..in order to open this website on my PC..
iam currently using IE7 and Firefox 3 browsers..and my PC model is compaq presario 1530 IL
OS- windows XP Pro sp3
Ram- 512 md
HDD-80 gb
ISP-BSNL Broadband

kindly help me

Well i dont think there is a problem

it might be that mobango servers were off wen u tried
