Now even Jio has started blocking websites

According to a post on Reddit Jio has now started blocking websites as mandated by the DOT earlier it was not blocking any websites. Source

It would be great if someone can paste the souce code of the page that is getting blocked here. We can then try and see what tech they are using to block the sites.
@a2642605 Thanks for that. So they are also using Netsweeper as well.

@Sushubh Well here we go another major ISP which uses Netsweeper. Should this lead us to believe that Netsweeper is indeed the industry standard and most use it to enable blocking?
