Statement Regarding ACE System Outage

Release Date

At approximately 3:30 p.m. EST today, CBP experienced issues with the Automated Commercial Environment (ACE) database.

As a result, the ACE Portal is currently unavailable to all users and the system is unable to process EDI messages. All transaction processing is currently unavailable, including cargo release, all modes of manifest, and entry summary processing. CBP is unable to arrive conveyances electronically in any mode at this time. Access to AES Direct is also inhibited due to the unavailability of the ACE Portal.

Immigration, passenger processing and other border security systems are not impacted by this ACE system issue. Our technicians are working vigorously to identify the source of the issue affecting the database.

At 4:57 p.m. EST, CBP provided instructions to the field to invoke downtime procedures at all ports of entry. These local downtime procedures were established consistent with national policy and activates communication networks within the ports of entry.

CBP executive leadership is in communication with our ports to ensure maximum cargo facilitation while maintaining border security and enforcement. To that end, express facilities have been authorized to staff as needed to facilitate the night package processing.

We recognize that this issue may be causing a significant disruption to the clearance of cargo. All available resources are dedicated to restoring full ACE system availability as soon as possible.

CBP will continue to communicate regularly with our internal and external stakeholders until ACE is fully available. For issues that require immediate resolution, please contact your local Port of Entry.

Once we have communicated that ACE is fully available, please contact your Client Rep or the CBP Help Desk if you are continuing to experience ACE filing issues.

Thank you for your patience and support as we continue to work through this critical issue.
