Here is a silly little site that can keep you from going wild.
Have you ever wondered if the site you want to visit is offline or if there is a problem with your connection (router, proxy, etc.)? Access the site Down For Everyone Or Just Me. Write down the URL in the field and click or just me? After validating the link, the service tests it and returns the result.
Down For Everyone Or Just Me will then tell you if the site can be reached from its server or if it is only a problem that arises for you. Then it's up to you to see if there are any problems on your side.
This online service is satisfied with the bare minimum: a text box where you enter the address of the site you wish to test.
No need to explain how Down for everyone or just for me works since there are absolutely no options (I told you it was a minimalist service). Simply enter the URL of the site that is no longer responding and query the machine. In less than a second, depending on the response given, you know if access is unavailable for everyone or if you are the only one affected.
