(NEW YORK) — Flights are back up and running Thursday morning after U.S. Customs and Border Protection systems at U.S. port of entry airports experienced an outage lasting up to 90 minutes Wednesday. The glitch caused long delays for international passengers.
The system, which is part of a multiple redundancy security check, cross-references passengers in databases like the CIA and FBI looking for expired visas and other questionable information.
Sources at U.S. Customs say the outage was part of a “typical” occurrence and was not nefarious in any way. Airlines and agents are usually notified immediately when it goes down.
The airlines still don’t know how widespread the outage was, but agents were forced to use alternative processing procedures until the system was restored.
