An error on Google’s part has caused widespread Internet outages in Japan for about an hour, on Friday, August 25. The downtime was caused by a BGP route hijack that began at 12:22 PM local Japan time and was resolved by 1:01 PM. The issue was resolved in under 40 minutes but was enough to cause panic in Japan. A Google spokesperson admitted the company’s blunder in a statement to another local news outlet. NTT Communications Corp., a major ISP who also supports two smaller ISPs named OCN and KDDI Corp.
