For something more sophisticated and less manual, use ekalinin/awsping.
The below script will ping every region (or a subset of regions) and output the latency.
Here's the full list of AWS regions as of November 2022:
- Africa (Cape Town):
af-south-1 - Asia Pacific (Hong Kong):
ap-east-1 - Asia Pacific (Tokyo):
ap-northeast-1 - Asia Pacific (Seoul):
ap-northeast-2 - Asia Pacific (Osaka):
ap-northeast-3 - Asia Pacific (Mumbai):
ap-south-1 - Asia Pacific (Singapore):
ap-southeast-1 - Asia Pacific (Sydney):
ap-southeast-2 - Asia Pacific (Jakarta):
ap-southeast-3 - Canada (Central):
ca-central-1 - Europe (Frankfurt):
eu-central-1 - Europe (Zurich):
eu-central-2 - Europe (Stockholm):
eu-north-1 - Europe (Milan):
eu-south-1 - Europe (Spain):
eu-south-2 - Europe (Ireland):
eu-west-1 - Europe (London):
eu-west-2 - Europe (Paris):
eu-west-3 - Middle East (UAE):
me-central-1 - Middle East (Bahrain):
me-south-1 - South America (São Paulo):
sa-east-1 - US East (N. Virginia):
us-east-1 - US East (Ohio):
us-east-2 - US West (N. California):
us-west-1 - US West (Oregon):
us-west-2 - AWS GovCloud (US-East):
us-gov-east-1 - AWS GovCloud (US-West):
us-gov-west-1
And here's a quick POSIX/BASH script to ping all (or some) of them:
#!/bin/sh
