The Defense Travel System (DTS) will be offline on Thursday, December 18, 2025 starting at 8:00am Eastern time due to a Continuity of Operations (COOP) exercise. DTS should be back online by 4:00pm Eastern time that same day. The Enterprise Web Training System (EWTS) will also be unavailable.
This COOP exercise is a requirement of the Federal Information Security Management Act (FISMA) and we appreciate your patience as we fulfill this mandate. While we are confident that there will be no difference in system functionality, users are encouraged to verify that all recent actions completed in DTS prior to the exercise successfully transferred after December 18, 2025. Analysts will closely monitor the exercise to identify any impacts to the user community.
