Find the lowest latency Azure regions from your place using azping

azping is a command line tools that help you find the lowest latency Azure Region from your place. It acutally reports median latency to Azure regions. It is a fork of gcping.

What does azping actually evalulate?

azping evalulate the median latecy of http requests to Azure blob storage endpoints located in each of Azure reagions from your place. Number of requests to be made to each region is 5 by default, but it can be changed with -n parameter that you can give in executing azping command.

Here is a list of Azure blob storage endpoints that azping evalulates:

NOTE All blob storage endpoints are created with the following scripts (Just in case I leave the procedures):

$ git clone https://github.com/yokawasa/azping.git
$ cd setup
# Edit RESOURCE_GROUP and REGION_LIST variables in env.sh
$ vi env.sh
# Read variables as enviroment variables
$ source env.sh
# Execute the following script that execute the following|
# (1) Create resource group for azping
# (2) Create blob storage accounts in each of Azure regions
# (3) Create $root container and upload ping file to the container
# (4) Check accessibility to all blob storage endpoints
$ ping-entrypoint.sh
