If the browser is failing to load the statcounter.com domain than there is a connection problem. We've not had any outages that would cause this or any other reports.
A good tip for connection problems is to change your DNS to OpenDNS. It's used by Nike, Amtrak, British Petroleum, and many other big companies. The best part is it's 100% free, doesn't require you download/install anything and only takes a few minutes to setup.
