The FAA’s air mission notification system NOTAMs (Notice to Air Missions) experienced a serious glitch on Wednesday, temporarily grounding flights across the United States. The FAA said it initially judged that the source of the problem was a damaged database file, and there was no evidence that it was a cyber attack. The backup system of NOTAMs was also found to have corrupted files. The computer problem arose late Tuesday, and the FAA responded by restarting the system in the early hours of Wednesday morning, when there were fewer flights. It took 90 minutes, but the system was not fully functional after the restart. A nationwide grounding order was issued at 7:30 a.m., causing massive flight delays and paralyzed airports. The FAA accident underscores the need for a massive overhaul of its aging infrastructure. The FAA delayed the technology update because of budget concerns, and people familiar with the matter believe the agency should now be looking for a budget to update the system.
