On Monday 21.07.2025 at approximately 18:01h (CEST), PRISMA was made aware that shippers had problems placing bids in within-day auctions. At this point it was not yet clear, if those were isolated issues, or a platform incident. After additional shippers reported similar problems in the following hours, the classification as platform incident was made at 19:57h (CEST).
Caused by legacy code in the frontend, shippers were not able to place bids by using the “place bid” button on the network point details page. Placing bids via the auction tiles (by accessing the overview of all running auctions) and via the “Auctions at this network point” section on the network point details page was possible during the entire incident.
In total 4 shippers reported issues with placing bids. Out of those only one shipper reported that they were not able to place a bid at all. This led to the cancellation of one within-day auction.
The total duration of the incident from classification on 21.07.2025, 19:57h (CEST) to resolution on 22.07.2025 08:44h (CEST) was 12 hours and 47 minutes.
The fix for the “place bid” button was deployed on 22.07.2025 16:00h (CEST), restoring full bidding functionality for the “place bid” button on the network point details screen, which is an additional 7h and 16 minutes.

Deploy fix |
After implementation and testing a fix was deployed to PROD. |
Cause: Faulty code in the legacy frontend prohibited users to use the “place bid” button for placing a bid in an auction. After clicking on the button the platform showed an error screen with the information that an unknown error occurred. The general bidding functionality of the platform was not impaired, since placing bids from other parts of the GUI worked throughout the entire incident.
Assessment: Incident was most likely caused by a side effect of an unrelated change and the existing regression and end-to-end tests did not catch the error.
Detection: The problem was identified by a user report. Shippers contacted PRISMA’s Customer Success after experiencing issues with Placing bids.
Intermediate resolution:
PRISMA pro-actively communicated that bidding is possible via the auction tiles (by accessing the overview of all running auctions) and via the “Auctions at this network point” section on the network point details page. The communication was done by publishing a UMM and by Customer Success, when contacted by shippers.
Long-term resolution:
On 22.07.2025 at 16:00h (CEST) a fix was deployed to production, which corrected the error.
Restoration of service:
The bidding functionality was not fully impaired during the incident. Following the discovery, reproduction, and verification of the frontend error, PRISMA provided guidance to shippers on the frontend locations where bidding remained available.
Preventive Actions:
