There are a couple of web services that allows you to check whether the given website is accessible from other countries or not. Just-ping.com is one of the free service with same features. It is much more powerful than other ping services as it has 30 monitoring stations world-wide including USA, India, China, Turkey, Saudi Arabia and more.
To start all you have to do it visit the website here and ping a server or website simply by typing your domain name then clicking ‘Start‘ button and their network (of over 30 monitoring stations worldwide) will provide you the results.
In a few seconds the webservice will show you the results table. First two results table columns (Checkpoint & Result) are very important. If result column shows ‘Okay‘ then Ok but if the ping results says 100% Packet Loss then most likely that website is inaccessible on that region.
