Amazon Cloud is available in multiple regions and this tool will help you measure the latency from your browser to different regions. Click on the check latency button below to get started.

I would say from absolute latency perspective, it's not very reliable. However you should be looking at the relative value of the observed latencies for each AWS region to identify which are best AWS regions for your location.
We are making a HTTP GET request to AWS Service Endpoints (like EC2, SQS, SNS etc) for PING and measuring the observed latency for it across all regions.
It means Not Applicable and when a specific service like SimpleDB is not available in any AWS region, we will display NA instead of latency.
