I am want to check if the content blocked by your organisation. Is there any way by which I can make sure that the content is blocked or not?
To check whether the content is blocked or not you need to try to access that content and then according to the error message receivedwe can interpret that if the content is accessible or not. Let us consider they have blocked the Google domain. Then you will have to access Google.com through any web browser if the error message is that the content is inaccessible. Then you can be sure that the content is blocked by the organisation.
But if you are getting other messages like page not found or if you get themessage as no internet connection. It has different meanings.
