Why Microsoft routed example.com traffic to a company in Japan

Why Microsoft routed example.com traffic to a company in Japan Source: Ars Technica arstechnica.com/informati… Microsoft has remediated an unusual network anomaly that resulted in traffic destined for example.com—a domain reserved exclusively for testing—being routed to an electronics cable manufacturer located in Japan. Under RFC 2606, an Internet Engineering Task Force (IETF) standard, example.com is not intended to be reachable by any organization. Instead, it resolves to IP addresses assigned to the Internet Assigned Numbers Authority (IANA). This designation is designed to prevent unintended traffic from reaching third parties when developers, penetration testers and others require a non-routable domain for testing or documentation purposes. Alongside example.com, the domains example.net and example.org are similarly reserved for this purpose. Developers are explicitly instructed to use these domains instead of live, Internet-routable addresses to avoid accidental traffic exposure.
