Cable news is broadcasted 24-hours a day, 7 days a week, from multiple locations across the globe. I would estimate over 50 interviews from various locales are conducted on any given day over each cable network (i.e. Fox News, CNN, and MSNBC).
When NFL player Benjamin Watson was on CNN talking about his popular Facebook post regarding his reaction to the Ferguson, Missouri, grand jury decision to not indict Officer Darren Wilson, he was abruptly cut off seconds after mentioning "that Jesus Christ died for our sins."
Was this an actual technical error where the signal was freakishly lost from the warm and cozy studio in New Orleans? Highly unlikely. If Watson was in a tropical storm or in a foreign war zone, perhaps a connection could be lost, but this is pure censorship.
