Betfair experienced some instability in the API this afternoon, running from about 15:00 through to 16:30.
A number of markets were affected and may have resulted in TBE being left in an unknown state. In particular, the 15:50, 16:05 and 16:15 races appear to have been adversely affected.
It may be necessary to restart TBE in order to ensure that the markets are closed correctly.
Apologies for the inconvenience.
