That is what I am asking @Karan how are they even able to block https:// websites. Isn't https:// supposed to be a secure protocol that can't be breached by people who want to snoop the data being transferred like ISPs such as Airtel. How are they blocking and snooping https:// connections?

@Sushubh Please share your insight if you know how they are able to do this?

Edit: I should add that the website I have given the example of is using a Cloudflare certificate.

ssl certificates have domains listed in them. one possibility is that they are reading ssl certificates before loading the website. they read one of the blocked domains in the ssl certificate, they block access to it.

HTTPS isn't something that can't be blocked at all. There are many ways it can be achieved. I am not sure of the exact method they use, but being an ISP with hundreds if not thousands of network engineers working for them, it should not be to difficult. Remember, they aren't injecting data into your https stream, which is what https is mainly used for, end to end data security/integrity. They are simply redirecting you to a block page in the event you are accessing a webpage on the block list.
