ACE Certification Maintenance Window Scheduled July 15, 2026 (5–8 PM ET)
CBP has scheduled a standard invasive maintenance window for the ACE Certification environment on July 15, 2026, from 5:00 p.m. to 8:00 p.m. Eastern Time. Testing and certification activities in ACE will be unavailable during this window.
Broker's Take
This affects the certification/test environment only, not production ACE filing; however, software vendors and brokers doing pre-deployment testing should plan around the outage to avoid delays in system validation.
