Starting yesterday, we’ve noticed the search engine DuckDuckGo being blocked via DNS in India. Specifically, users using Airtel or Tata DNS servers. Other search engines are fine (Bing, etc.,.). I know alot of blocking is occurring in India recently, but I think the net was incorrectly cast over this one. Its not all ISPs in India, so far just Airtel and Tata. $ dig @122.166.234.70 duckduckgo.com ; <<>> DiG 9.10.6 <<>> @122.166.234.70 duckduckgo.com ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 7316 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4000 ;; QUESTION SECTION: ;duckduckgo.com.
