The breakdown caused the processing of thousands of people arriving from abroad to be slowed.
The Department of Homeland Security said in a statement that "U.S. Customs and Border Protection is experiencing a temporary outage with its processing systems at various air ports of entry and is taking immediate action to address the technology disruption."
Reports of frustrated travelers were on Twitter Friday afternoon.
LAX is one of many airports that is impacted.
