So recently I had a problem with a website not working from another country but it worked fine for me. So I started a few routine checks.
First try to see if its down just for you or also a US server “: Is it up or just me” :
Net you can try a proxy :
https://hide.me/en/proxy to see if your ip was blocked
Last you can try this online ping that allows one to check ping from many multiple other countries.:
Now if you want to consistently making sure your site works for all other countries as well you can use pingdom.
