Passport systems back online after brief outage disrupts U.S. airports

Long lines of people waiting to go through customs at Miami International Airport due to a reported computer issue

U.S. Customs and Border Protection said Monday that all systems were back up after a temporary outage caused delays at airports nationwide.

The outage began at about 7:30 p.m. EST (0030 GMT) and was resolved about 9:30 EST (0230 GMT), the agency said in a statement.

Global travelers at multiple airports took to social media Monday evening express their displeasure after they faced delays and long lines during processing.

Dallas/Fort Worth International Airport also tweeted about a "system issue affecting processing times for customs". DFW International was one of the airports affected.

For roughly two hours, the customs computer systems were unable to recognize who was a US citizen, a resident or a visitor, so everyone had to go through an immigration officer, making the process much longer. It said Monday night that all airports were back on line.

During the outage, CBP said it had access to security-related databases, so travelers were still screened according to security standards. Delays were caused because the CBP-controlled passport-processing systems were down.

CBP officers continued to process worldwide passengers using alternative procedures, but the agency acknowledged that travelers at some ports of entry experienced longer than usual wait times.

During the outage, "alternative procedures" were used to process global passengers, according to the agency.
