Site Loading Issues

For some reason my site is not loading properly. I called Go Daddy & they did system checks on their end and said on their end things were fine. I keep getting “Problem loading page” messages, the connection was reset. When I hit try again, then it loads. This just started happening today. Also, just today, all my posts that I put on facebook are not loading with the photos. I tried using the https://developers.facebook.com/tools/debug tool and my links are coming up with bad response code which is odd because I’m not posting any different than usual.

Any thoughts to this matter?
