My inclination is that this is an internet or device issue- either your router or device is blocking the website for some reason and needs a flush. If you clear your cache and cookies it'll likely resolve.
I don't have a problem getting to this site. It's only when I try to log in or post. I sometimes have to hit enter 20 times or more for it to go through. I've cleared cookies, cash and everything else. I don't have problems any where else.
