The WWE Network is currently down. I loaded the live feed page and the feed is not working. It looks like the issue has been ongoing since the 5 AM EST hour as the "Up Next" programming is for the 6 AM ET and 7 AM ET hour.
So far, there has been no acknowledgement from WWE about the outage.
March 5, 2014 9:12 AM EST Update: I just reloaded the page and it's back online. We still do not have confirmation as to how long the service was out. End update.
