During observations for the delayed receipts. The team noted increased i/o latencies at times to service requests on one of our databases going back to 5am. This will have resulted in increased response times periodically to APP and API requests. At 15:21 GMT requests were failed over to a different instance. Services appear to be operating as normal, the team will continue to monitor performance over the next hour before closing the incident. We apologise for any inconvience caused.
