Looks like Betfair may have had some wobbles again this afternoon.
They are currently looking at some issues that started just before the 16:00 race at Kempton.
Personally I saw comms issues to Betfair from just after 16:00 through to around 16:06.
Betfair are investigating a "freezing" issue with their data providers. Net result is that there was no market data available between 16:02 and 16:06, which means that the latter part of the 16:00 Kempton race and the 16:05 Fairyhouse race were affected.
