GBP 'faster payments' down for maintenance

Is the ability to make faster payments in GBP actually down for maintenance or is this due to the FCA action against Binance still meaning this way of paying isn't allowed.

I previously used this way of making payments because I didn't get stiffed for 1.8% when using my debit card and the exchange rate was much better. Is there perhaps an alternative way of keeping costs low if faster payments isn't going to be available for a while?
