WordPress Down?

2 of my www.remarpro.com sites with advanced theme templates are not operating properly this mid day. I cannot log in. When I was logged in the page was taking forever to load. Changes were not not taking place that I made in theme. Now I cannot even get the web page to load in the browser? I thought it might have been the server but my other sites are fine. As are some of the WordPress sites in an older version.

Is is everyone or did I do something?
