The FAA lifted a nationwide ground stop this morning and normal operations resumed at about 9 a.m. EST after an outage of the agency’s Notam system forced the cancellation of more than 800 flights and delayed nearly 5,000 more. According to the OpsGroup, the system failed at 3:28 a.m. EST and had processed no new Notams until about 9 a.m.

Newark Liberty and Atlanta Hartsfield-Jackson airports were the first allowed by the FAA to resume flights due to the level of traffic congestion at those major gateways. The outage stood to affect flight schedules throughout the day as airlines work to mitigate a cascade of disruptions.
