   Marqeta Engineers have observed elevated STIPs on the Pulse network impacting some cardholders utilizing the Pulse network starting on 11th of May at 10:20 PM PDT. A dedicated response team has been assembled and has identified the technical issue as a processing failure within our systems when encountering a new data pattern originating from the Pulse network. To mitigate the impact and confirm the necessary fix, we have engaged the Pulse team for clarity on this new data behavior, and Pulse has raised an incident from their side to investigate. We will provide an update as soon as we have confirmation of the fix and an estimated time to resolution."
