The circumstances where the GRDA receives messages after 02:59:59 should be exceptionally rare – i.e. systems have failed in normal operation; the resilience built into the system to maintain contiguous service have failed such that they cannot be restored within the 1 hour RTO; Target DR Recovery has been missed AND Maximum DR Recovery has also been missed.
Since this change is required in such rare circumstances this change needs to identify a solution that is cost effective to implement so that these Registrations can be recorded in UK Link systems.
The analysis needs to engage stakeholders to determine the risk / impact of the solution to all industry participants.
This change should focus on short term options for implementation. It is not proposed to initiate a large investment given the extremely low likelihood of this scenario occurring.
