Google not opening on bsnl broadband ?

I am using bsnl dataone broadband and I am happy from it so far but sometimes site like google does not open but other work fine. Even today I am unable to search anything in google from last 1 hour since I open internet today.

Do any other bsnl bb user face same problem sometimes ?

I am also a bsnl user. I do not face similar problem.

may be just look at fire wall setting to see if by mistake Google is not in block list

Well.. Now I do not face that problem anymore !
