From 14:37-14:40 BST and then again at 15:04 to 15:17 BST, Form3 experienced a degradation where account validation services were temporarily unavailable for payment processing.
This resulted in a small number of admissions not being handled within normal timeframes, timing out and showing as reversed in the Form3 API.
Form3 identified that this was as a result of unexpected platform behaviour linked to a routine release. The release was rolled back, the service stabilised and processing resumed as normal.
We are reviewing the change as well as our testing suite to ensure this behaviour is identified as part of the change testing process in any future releases.
