Not sure how true this is, but looks like government of India had odered information ministry to block blogging sites. As I have seen, the first one to get impacted is Google’s Blogspot. Home page of this blog site is available but the individual blog pages are not..!! If true, this is against freedom of speech. You cannot stop people from voicing their opinions by blocking blogging sites
