Hi
As from Tata AS6453 looking glass: Router: gin-laa-mcore3 Site: US, Los angeles, LAA Command: ping ip 216.6.87.114 Sending 5, 100-byte ICMP Echos to 216.6.87.114, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms So basically that IP/router is in US but you getting high latency because of return path which is likely via East Asia. As Joel rightly pointed out - end to end latency is just fine in this case. Have fun!
