An overload in the Container Track&Trace system was caused by a number of heavy-load tasks executed at the same time. As a consequence, the CTT Web Application and the CTT API were not available for approx. 90 minutes during the night. After stabilizing the system, one subsystem was still blocked on Sunday, and tracking updates were not processed and displayed or delivered. As soon as this block was lifted, tracking data was automatically backfilled and delivered. No data was lost.
We apologize sincerely for the delayed and incomplete communication around this incident. We are taking measures to prevent this kind of overload in the future, as well as to ensure proper communication.
