Betfair have made the following statement:-
This afternoon we had a problem on the sports exchange where markets were not loading. In accordance with our Customer Charter, a decision was made to disable ALL betting, which was implemented at 15:50:51 BST. Our technical teams resolved the issue, and betting was re - enabled at 16:04:09 Below is our process cancelling bets during an outage.
Will my bets be cancelled?
We will now cancel unmatched bets in the following instances:
* Unmatched bets on markets which are In-Play at any time during an outage.
* Bets which, when an outage ends, are unmatched on horse and greyhound races that are due to take place within the next 20 minutes; also, financial markets bets which are unmatched at the start of an outage. These markets are included because they are particularly volatile and are subject to notable odds fluctuations.
* Bets which, at the moment betting is disabled, are unmatched on outright winner markets where there may be material price changes due to related In-Play events. For example, a tennis tournament winner market when a tournament semi-final is taking place at the time an outage begins.
