> Meanwhile, DuckDuckGo confirmed on Twitter that it’s looking into the issue and suggested Android users change their DNS provider to get around the issue.

If changing DNS works, how is this blocked by the ISP? Seems to indicate there is some other technical problem. Treat the rest of the article, and specially with tweets, with skepticism.

Haven’t been back in India for a while, but the DNS blocking happens all the time. One big provider (AirTel) even injected ads in non-https pages quite frequently.

Anecdotally, I had a cable service in Delhi where the provider started throttling me if I didn’t make any request to their dns server in some arbitrary time interval. So changing your dns might not be the fix (i fixed it by sending random queries to their server...).

...and in "HTTPS" pages "secured" by cloudflare. https://medium.com/@karthikb351/airtel-is-sniffing-and-censo...

It would have been nice to have a more proactive response in the original discussion on this: https://news.ycombinator.com/item?id=12092188

Denmark does the same thing for illegal gambling sites, sites selling medication illegally and file sharing sites. Basically it's just the courts telling the ISPs that their DNS servers can't resolve certain domains names any more.

Everyone accepts that it's pretty easy to bypass but it's considered "good enough".

ISP's DNS, which you use by default, has a blacklist.

You change your DNS, no longer see ISP's blacklist.

IIRC Cloudflare (1.1.1.1 and 1.0.0.1) also support encrypted DNS.

They simply filter out DNS records on their caching DNS server that they provide to their users.
