I use vodafone for internet and my experiance is that there server is always ok. I also know that it may be little bit costly than other but there service is best . I have also bsnl broadband connection but you cant trust on bsnl . There is no time for server down.
So I used this net( vodafone pack in my mobile) for safety reason if other internet will down then vodafone internet will save my work. Thanks vodafone. Zozozo
