As the title said, I've encountered sereve network connection issue when I'm using KDDI Japan's network (via Linode). I've confirmed there's nothing related to Linode (other regions' network connection is OK). But I almost cannot connect to my services in East Asia(High latency and low speed). And Traffic Manager would respond queries with East Asia's IP address instead of Japan West's IP address, though I've added a Japan West endpoint.
I believe there is something wrong with Azure East Asia Datacenter's network connection.
