You’re trying to check your e-mail account or your favorite online news site… but the homepage just won’t load. Is it your computer? Maybe you have a virus. Maybe you have accidentally enabled a setting that’s blocking the site. Or is the website itself down? It can be a frustrating as you try to load the page again and again, with no luck and no idea what’s going on.
Next time this happens, just enter the "broken" Web address at downforeveryoneorjustme.com. It will tell you if the website is accessible to other users. If it is, then you know to start looking at your own computer for the solution.
