What to know if one of the services you use is down or not? Well try downornot.com this website can tell you if a website is down or up. It checks the website with many different servers from multiple locations. This website is usually correct but sometimes it can be wrong. The only thing is the website only does certain websites like facebook, netflix, thepiratebay, youtube, and google. So you can just enter any url which would make it nicer but it still works.
If you want a website that will let you check any website you can use something like Down For Everyone Or Just Me it has a long name but it works. The only thing I don’t know if it is as good as down or not, with all my testing it correct everytime I used it. Down For Everyone Or Just Me has a very simple and easy to use interface.
