I've been having similar issues.

Last week I was unable to access opendns.com, and because I was using them as my DNS, I couldn't get to any site, so I had to change my DNS settings until I got it fixed.

I can now connect to the site, and use them as my DNS but it ended up being my ISP was blocking me out. I have no idea why.

If your router supports it, try pinging the site straight from the router. I have a page on my router where by I can ping from the router. That way you can find out if it's just your computer, or if it's your whole internet connection.
