The report continues, "The outage that started in the early hours of Sunday [Oct. 27] caused the data center to lose network connectivity with the federal government's data services hub, an electronic traffic roundabout that links the online health insurance marketplaces with numerous federal agencies and can verify people's identity, citizenship, and other facts...Obama administration and [Verizon] officials could not say how long it would take to fix the connectivity problem."
