Buckeye cable > Comcast 
They are having issues right now. I went in and replaced my DNS servers a when this all started and haven't had issues since. They've decentralized their dns servers again so the problem should be going away. If you have a router, I suggest rebooting it so that it will get the latest dns servers or set your dns servers to any number of the ones available publically.
