On Monday 10th November Betfair forced all existing API users over to their new API-NG. Ever since there has been multiple problems with the API's level of operation. CUSTOMERS are experiencing short periods of 'locking-up' on a regular (daily) basis. Inflated latency and slow Bet Placement. There have also been problems with events not going in-play. This is absolutely not good enough for customers Betfair, particularly those that are routinely charged 'Premium' commission to at 20 - 60% of profits.
