Site not loading

I’m not sure what version of wordpress we are using, but it’s usually updated to the most current version. Our site, bboutrigger.org is not loading- not for me or others. Now it says “Safari could not open the page because the server stopped responding”. I’ve also tried on Firefox. I can’t even log into the admin page. I’ve tried clearing the cache and cookies, but no luck. No one seems to be able to load the site, it’s been happening for at least a week now.
