Yep same issue here - it is like banging your head against a brick wall though, seemingly no one knows what the problem is, not me, my ISP, betfair or BA. It is affecting far too many people imo to just be coincidental, all the forums are seeing people having issues.
Though tbh, with all the issues last year which I and others suffered from for months on end no one knew what the issue was or would take any responsibility. It seems to be a very similar issue as that was and that after months and months of badgering, emails and telephone calls and an awful lot of lost trading days and in turn profits was eventually discovered to be an issue with Betfair who eventually replaced hardware. Despite for months on end saying there was no issue there end and all tests we showing things were fine with them.
So I would not rule out that being the issue again here. In fact if I were a betting man and not a trading man I would put money on it being an issue at Betfair's end
So I have resigned myself to just accepting degraded service and am just learning to cope with it as I cant afford to lose as much money to it as I did last time round.
Though to be fair both Neil at the Betfair BDP department put in sterling efforts as did all of the Bet Angel team. Lets hope it is however just a minor blip and not a return to the months on end of poor performance.
