Last Friday, the Internet in Japan worked with significant interruptions. The fault was Google's mistake, and although the problem was fixed in a few minutes, it was enough to sow panic and leave most of the country's population without access to the Internet.
It was reported that the error was allowed in the BGP dynamic routing protocol. Google experts incorrectly announced blocks of IP addresses and, in fact, carried out the so-called BGP hijacking, as a result of which Japanese providers, including such a giant as Verizon, began to massively route traffic to search engine servers. And since Google is not a provider and its server is not designed to work with "left" traffic, the data transmitted by residents of the Land of the Rising Sun simply went to nowhere.
It is noted that the disconnection of the Internet in Japan did not lead to any emergency situations. Nevertheless, the Interior Ministry still initiated an investigation into the search engine.
Google has already made an official apology, but they did not clarify whether the incident was the result of a hardware failure or the fault was a human factor.
