“DNS queries to all servers are blocked if you try to get a blocked site's IP”
Wait, so if I was in Turkey, a request for wikipedia.org to my ISP DNS server would not only have failed, but caused all my other queries to fail as well? For how long?
I think I couldn't explain well.
When we use ISP's DNS, we get a local IP address and a web-page at that address, explaining who blocked the site and why.
But if I use Google's or Cloudflare's public DNS, the query won't get an answer, falls to timeout.
A funny method to circumvent the block was to visit wikimedia. As long as your connection was kept alive, you could keep surfing wikipedia like it wasn't blocked at all!
This worked well in domestic telecommunications providers. Universities implemented the block themselves, and you were unable to use the workaround stated in those universities.
