Yesterday, typing randomly in the search box google.com (namely .com) request (the word test in the Russian layout), found the contextual content, which is shown in the picture. Either tested and forgot to remove, rolling in production, or whether it is such an interesting announcement. The thought about the error was suggested by the fact that I personally often specify test.ru as a test domain or test@test.ru for email, and checking if there is internet, I ping ya.ru (sorry).
