Network Latency Between Amazon AWS Regions US West-1 and US West-2
We recently had the opportunity to measure the network latency between an Amazon AWS instance in the AWS region US West-1 (Northern California) and one in US West-2 (Oregon).
TCPing and traditional ICMP Ping were used, the machines were Windows Server 2012. 1,500 observations were, taken, about once every minute (Feb 5, 2013).
Median : 31.2 milliseconds
Mean : 31.7 milliseconds
95th percentile : 31.2 milliseconds
Median : 20 milliseconds
Mean : 20.6 milliseconds
95th percentile : 25 milliseconds
