I found this as a link on a 404 page. It’s a great way to redirect people back to your site, if all is well. If not, then they will know your site is actually down.
Type in your own link if you want to check your own site. But, it really seems like a better option for 404 pages than checking your own link.
If you are having trouble getting a site to load and you don’t know why… clean your browser cache. Surprising how often that works.
