Yes, this sounds like a connectivity problem.
There are websites where you can enter some other website's name or IP address (if you know it) - or, although these services often say "website" really they mean any online service, eg a mail server ... and they will tell you if they can see it (ie get a response when sending a test command to it).
Some of these sites only test from one or two places, while others run the test from many places.
That matters because the route between you and the server you are trying to talk to is quite diferent in different parts of the world. If the machine you are trying to talk to doesn't respond to anyone then either it is down, or something in the route to it that is close to it is down. On the other hand, if eg a substantial part of the internet is not functioning in France, then people there will be out of luck but people elsewhere will see no problem.
Sites I regularly use for tests are:
