If you are interested in knowing how a website you visit (or a website you manage) is ranked by Google you can use the the PageRank Status extension for Google Chrome.
Looking for a website and keep getting an error page? Is the website down or is there a problem with your internet connection? If you operate a website you will definitely hope that it is a simple isolated problem with your computer or your internet connection and that others can still access your website. Down For Everyone Or Just Me is a service that tells you if a website is currently online or offline.
