AWS Region Latency

There's some cool websites like CloudPing.info that can tell you the approximate ping between your physical location and a cloud provider's datacenter. The website pings the https://dynamodb.REGION.amazonaws.com/ endpoint and listens for a response. However, CloudPing sends each request sequentially and runs kinda slow. I wanted to challenge myself if I could make one that shows you the information faster.

This version of CloudPing uses Promise.all to parallelize the fetch requests from DynamoDB. It also uses the high resolution resource timers built into your browser to get an accurate ping from all AWS regions.

I haven't got my IP address blocked yet for abusing the DynamoDB endpoints, but if you'd like we could all try together?
