"The station's main production switcher experienced a critical failure late Tuesday evening," Robertson said in an email response to the Sun. "The equipment failure prevented the news broadcast from starting on time at 11p.m. Between 11p.m. and approximately 11:07p.m., WJZ aired a repeat of the CBS Evening News. Technical personnel responded quickly and were able to repair the problem. WJZ's local news began just before 11:08p.m."
