The problem is with Level3, one of the biggest bandwidth provider in USA. Their network is down and many locations are not accessible now.The Newshound can be accessed through this link, but I can't say whether everything will work for you or not.
Our own netwok is fine and there is nothing we can do on our end to fix the problem.
The Level3's techs are working on the problem and we expect it to be fixed soon.
You can track the status of the problem here.
UPDATE 12:13: All the problems seemed to be resolved around 9:30 (4:30 EDT).
