On 09 December between 09:50 - 12:59 UTC, there was a degradation to FPS test payment processing on the FPS Simulator. Outbound payments were stuck in released_to_gateway and inbound payments were not received. Any test payments impacted during this period will need to be replayed.

Investigations identified that Form3 testing was being carried out in the Staging environment, in relation to a planned non-customer impacting change that was scheduled for deployment to in Production. The testing, combined with the planned maintenance that was underway resulted in the Staging simulator not being in a high-availability configuration. A change has been made to amend the CI simulator deployment to be in a high-availability configuration to prevent a future reoccurrence.
