X-rapid live at FI since 18th of Jan?

There seems to be some evidence from the xrp ledger that a deployment of x-rapid may have been live since the 14th-18th of January. If not that, then at least some large Financial institution has been testing it since that time and may be ready go live soon. First, the payment ledger that has gone via Bitstamp has increased by a solid 4-5 million a day on average which would indicate some consistent use of either X-rapid or Corda Settler and second the number of ledgers and payments suddenly spiked and stayed high since the 14th-18th and they match up very nicely. I think this is very likely either a live deployment or a big test by a financial institution.
