Google said that the Turkish ISPs are blocking Google’s public DNS service that translates numeric Internet protocol addresses into domain names by enabling masqueraded DNS servers.
“We have received several credible reports and confirmed with our own research that Google?s Domain Name System (DNS) service has been intercepted by most Turkish ISPs (Internet Service Providers),” stated Google software engineer Steven Carstensen in a blog post. DNS servers tell your computer the address of a server in a way that is similar to how you look up a phone number in a phone book.
“But imagine if someone had changed out your phone book with another one, which looks pretty much the same as before, except that the listings for a few people showed the wrong phone number. That?s essentially what?s happened: Turkish ISPs have set up servers that masquerade as Google?s DNS service,” added Carstensen.
This news comes on the heels of the Turkish government blocking YouTube and Twitter. Why did the Turkish government block these online services? Bloomberg reported that YouTube was blocked after a leaked recording of a meeting where top officials discussed a possible military incursion into Syria was uploaded.
