Are any other browsers able to load the same page? How about if you change from wifi to mobile data (or the other way round)? How about a browser on a different device (like a laptop)? Localize where the problem is first. As of a little over 2 hours after you posted this, I can access the site, so it's not the site's problem - at this time. (That's not saying that the page just wasn't available when you tried it.)
