No, these sites are being blocked. I am on Airtel as well and things weren't blocked until yesterday. I think Reliance was the first to enforce the block - I believe they're also the ones who filed for the court order. It's really good to see this on the HN front-page, and hope there's more awareness / discussion. Blocking pastebin is a bit ridiculous :/ - the message one gets when one goes to any of the sites is just "This site has been blocked as per Court Orders", without any other explanation. Changing DNS servers does not work, so they are doing it at a different level.

tl;dr: sites are being blocked. wtf?
