From 07:23 BST we began to see a degradation of our FPS Indirect service leading to periods of intermittent instability, this caused some inbound payments to be reversed and some outbound payments to be delayed at the gateway.

The gateway provider identified the issue and implemented a fix allowing a move back to dual site
