It was, by the Federal Aviation Administration’s own account, a human error that brought down the agency’s Notice to Air Missions (NOTAM) system and in turn, lead to the halt of 32,578 flights within, out of and into the United States last Wednesday morning. The FAA said personnel failed to follow procedures during routine scheduled maintenance.
It’s called a cascading failure, said https://www.linkedin.com/in/nashcourtney/, internet incident librarian for IT continuous verification company Verica.
“They refer to that even in the FAA [incident] as a cascading failure.”
Such failure is particularly a risk with legacy systems, Nash added.
