I work as a researcher at the The Centre for Internet and Society (CIS), where we've been actively studying internet censorship in India over the last year. We've built CensorWatch…

We released a subset of the data along with the paper (~5K hostnames), can be accessed at https://github.com/kush789/How-India-Censors-The-Web-Data The app uses a more updated list…

Unfortunately we don't have the expertise or bandwidth to make that :/

I'm one of the authors of the paper in the post, we're trying to extend this work by crowdsourcing censorship measurements from different vantage points in India. We've compiled th…

Ah yes, my bad. I meant to say ESNI Read https://gfw.report/blog/gfw_esni_blocking/en/ some time back, recalled it incorrectly

You never know. Could be a mistake where they were trying to block a certain path due to some search result of copyright infringement, but ended up banning the domain itself. One c…

Well, they could block TLS1.3 entirely (which would force hosts to drop down to 1.2 for connections) GFC does this, I really hope it doesn't happen here

Haha yeah, I've been procrastinating for the last 5 years now

Yes! That's a great observation However, the reason I went for probing the entire path is because the TTL itself can be spoofed

Yeah there was a huge outcry about it on Twitter some time back. P.S. From the screenshot, it looks like you're trying to connect to [http]://duck.., hence shifting to https works.…

Yes, that was the case

I haven't been able to test that yet, neither am aware of any research which answers that question. IMO the only way to do that would be to either (i) block the IP (high collateral…

Using the TTL, we figured out that the censor kicks in at the kth hop. This kth box belonged to Airtel. If a box was censoring after Airtel, we would have received a clean response…

Thanks for running it! We are in the data collection stage at this moment, will definitely be publishing our findings and releasing the data publicly. P.S. Our previous paper talks…

I'm new to HN(3 months, low karma). Maybe that's the reason? Not sure what would be the correct way to "fix" this Thanks for vouching!

You can delete it after running. Each run on an (ISP, state) combination gives a new test point. Thanks!

DoH just by itself won't help unfortunately, since it just fetches the DNS (btw, only Airtel, ACT, BSNL, and MTNL bother with DNS censorship). ISPs have been looking at the clearte…
